1965 Impala Hell Project Part 6: Gauges! Switches! Buttons!

When we last saw the 1965 Impala Hell Project, it was the fall of 1990 and I was installing headers, dual exhaust, and a TH350 transmission in place of the original Powerglide. The car drove pretty well with those upgrades, but the fact that the entire instrument panel (except for the oil pressure idiot light) was kaput became quite an annoyance. Was the engine running hot? Was I going 80 in a 45 zone? How much gas do I have? Those questions remained mysteries, and finding functioning replacement parts for a then-26-year-old car in the junkyard would be tough. I had a solution, however; scavenging Pick-Your-Part for instrument-panel components on Half Price Day weekends and building my own instrument panel from scratch.

The factory instrument panel looked cool, but there was no way I’d be able to buy new replacement gauges on my recession-grade office-temp wages. Once I had all the parts I needed, a “DIP” street sign I found somewhere (no, I didn’t steal it) donated some high quality aluminum sheet and I was ready to go.

The car was developing some nice patina at that point; I’d taken to hitting it with black or gray spray paint whenever I spotted any sort of scratch or blemish in the gloss-gray industrial paint that the previous owner had hosed over the original Tahitian Turquoise paint.

After determining that just about all GM cars of the 1960s shared a common speedometer-cable connection, I scored this speedo out of a late-60s Buick. A Wildcat, perhaps? In any case, it was round, it looked cool, and the donor car had a similar differential gear ratio to the 3.31 in my Impala’s 12-bolt.

This is the only photo I can find of the aluminum panel that became the new dashboard (damn pre-digital photography era!).

However, I do still have the original diagrams I drew up to help with the wiring. They’re pretty thrashed, because they spent 10 years in the car’s glovebox. I got a lot better at this sort of thing a few years later, when I became a technical writer, but at least these diagrams are quasi-intelligible.

I used junkyard connectors scavenged from Toyota and Nissan wiring harnesses, with surplus wire bought cheap at the legendary (and now defunct) Mike Quinn Electronics. Quinn’s, as San Francisco Bay Area electronics geeks recall, provided much of the raw material for the Grateful Dead’s scratchbuilt sound system in the mid-1960s; a decade later, Jobs and Wozniak bought many of the components used in the prototype Apple I computer there. That gave my Impala provenance!

Most of the toggle switches also came from Quinn’s, but I decided to go Italian with the warning lights. Fiats used these beautiful metal-and-glass units in their cars for years.

Back in 1991, it was pretty easy to find Fiats in self-service junkyards, so I gathered a good-sized collection of stylish indicator lights. In fact, I still have a stash of them to this day (even after using many of them in the Junkyard Boogaloo Boombox a few years back).

When it was all assembled, my car had a cockpit that looked like something out of the Space Shuttle: Voltmeter, vacuum gauge, tachometer, speedometer, transmission temp, oil pressure, water temp, fuel, clock— everything from the junkyard. For switches, I had just about everything possible wired up, including a James Bondian taillight-cutoff switch and wiring for five separate horns (inspired by the multiple horns in my ’58 Beetle; unfortunately, I never did get around to installing additional horns in the Impala). The speedometer was mounted to the back of the instrument panel with a plywood spacer, and I installed red and green speedo-face lighting in the spacer (with a three-way switch to control lighting color).

The Kienzle clock came from a 1966 Opel Kadett, featured an Opel emblem and was the gauge that pleased me most. I’d found it in U-Pull-It Auto Wrecking in Oakland during my earliest junkyard expeditions, installed it in my Beetle during high school, and hung onto it long after the Beetle got crushed.

The factory AM radio was long dead, and I needed to listen to my collection of Motörhead and Public Enemy cassettes at all times behind the wheel. So, I broke out the plywood and the jigsaw and made this removable console unit to sit beneath the dash and atop the transmission hump (held in place with a couple of brass deadbolts). With eight junkyard speakers (four in the rear package shelf, two in each front door) driven by a pair of four-channel Brand X equalizer/amplifiers fed by a not-too-terrible Sony cassette deck (veteran of at least three of my previous vehicle dashes by that time), I had serious sound for next to nothing. Because I was parking the car in a lot of sketchy rip-U-off neighborhoods of San Francisco and Oakland at the time, I rigged my semi-unwieldy pull-out stereo with quick-disconnect harness connectors salvaged from junked Corollas. To remove the unit, I just pulled a couple of deadbolts and disconnected four harness connectors; it made for quite a conversation piece when I’d set it on the kitchen table at parties. I wish I had a photo of the front of the unit, but… damn pre-digital photography era once again.

Overall, this setup proved quite reliable, although I had to replace a few of the cheapo gauges over the years. At this point, the only real problems with the car, from a daily-driving perspective, were the four-wheel drum brakes and the lack of a heater. I solved those problems soon enough, as we’ll see in an upcoming episode of this series.

The skills I learned from this project proved useful in later years; when it came time for me to build the instrument panels for the Black Metal V8olvo race car, I was up and running in a hurry.

This setup remains in the car to this day, just awaiting its new owner to fly to California and get behind the wheel. Yes, I mean the legendary donk-racin’ Speedycop.

My 20R-powered ’67 Sprite, which now sits in the Evil Genius Racing on-deck-projects yard awaiting a narrowed RX-7 rear, also benefited from my instrument-panel-creating experience. See, working on Hell Projects pays off! Next up: Disc brakes, Generation X road tripping.

    Don't even get me started on how much hassle it was to cut the STEEL back deck of my '63 Nova to get those Jensen Triax speaker in there...

    Quite impressive! Can't wait for the next write up!

  • Jkross22 Their bet to just buy an existing platform from GM rather than build it from the ground up seems like a smart move. Building an infrastructure for EVs at this point doesn't seem like a wise choice. Perhaps they'll slow walk the development hoping that the tides change over the next 5 years. They'll probably need a longer time horizon than that.
  • Lou_BC Hard pass
  • TheEndlessEnigma These cars were bought and hooned. This is a bomb waiting to go off in an owner's driveway.
  • Kwik_Shift_Pro4X Thankfully I don't have to deal with GDI issues in my Frontier. These cleaners should do well for me if I win.
  • Theflyersfan Serious answer time...Honda used to stand for excellence in auto engineering. Their first main claim to fame was the CVCC (we don't need a catalytic converter!) engine and it sent from there. Their suspensions, their VTEC engines, slick manual transmissions, even a stowing minivan seat, all theirs. But I think they've been coasting a bit lately. Yes, the Civic Type-R has a powerful small engine, but the Honda of old would have found a way to get more revs out of it and make it feel like an i-VTEC engine of old instead of any old turbo engine that can be found in a multitude of performance small cars. Their 1.5L turbo-4...well...have they ever figured out the oil dilution problems? Very un-Honda-like. Paint issues that still linger. Cheaper feeling interior trim. All things that fly in the face of what Honda once was. The only thing that they seem to have kept have been the sales staff that treat you with utter contempt for daring to walk into their inner sanctum and wanting a deal on something that isn't a bare-bones CR-V. So Honda, beat the rest of your Japanese and Korean rivals, and plug-in hybridize everything. If you want a relatively (in an engineering way) easy way to get ahead of the curve, raise the CAFE score, and have a major point to advertise, and be able to sell to those who can't plug in easily, sell them on something that will get, for example, 35% better mileage, plug in when you get a chance, and drives like a Honda. Bring back some of the engineering skills that Honda once stood for. And then start introducing a portfolio of EVs once people are more comfortable with the idea of plugging in. People seeing that they can easily use an EV for their daily errands with the gas engine never starting will eventually sell them on a future EV because that range anxiety will be lessened. The all EV leap is still a bridge too far, especially as recent sales numbers have shown. Baby steps. That's how you win people over.
