I believe the car sold in Vegas has a single turbo - I believe it is a production Buick turbo setup. I happened to see it in Michigan before the auction and this is what I recall.

I'm not speculating here - I actually did this to my '65 and it works great. Without the diodes, you get a host of different inappropriate bulbs glowing at different intensities when you, say, turn on the courtesy lights when the doors are shut. I just used a pair of random single pole switches that happened to fit the openings in the hinge pillars - I'm not sure what kind of car they came from, but similar single pole switches are easy to find and are cheap & reliable. I spliced / soldered a diode into each of the three circuits per side, spliced the three (per side) into a single wire and connected it to the single pole switch. Works like a charm.

Crawl underneath and look at the the body mounts. They're prone to rotting too.

Hello Mr. Sweeney! My apology for taking so long to respond - it has been a while since I've logged onto the forum. If you study the wiring diagram, you'll see that the reason that there are three separate switches contained in each assembly is because there are three different sets of lights that illuminate when the door is opened. If you use a single-pole switch unit (like those used in almost every other car)and just wire all three to it, you will get current fed back into the other circuits when you, say, turn on the courtesy lights when the doors are closed. Diodes, if you're not familiar with them, only allow current to pass in one direction like an electrical check valve. By putting a diode into each of the three circuits (per side), you prevent this backflow so you can use a simple single-pole switch assembly. Of course you need to be sure to get the polarity right when you install the diodes.

I'd like to update my '65 Riv to interlocking engine mounts. I don't like the idea of the engine flopping around if there is separation of the rubber. Have any of you done this? Are ther any later mounts that are easily modified to work?

FYI - I've heard by good authority that GM is going to be auctioning one of the original '83 pace cars this fall. I believe it to be at Barrett jackson in Las Vegas in October. I believe it will not be the one that actually paced the race, but it is one of the ones used at the Speedway in 1983.

If you wire a diode into each of the three circuits (in the correct direction, of course) you can use any single terminal switch. I did this on my '65 and it works fine. It takes six diodes total -- three for each side. You can get them at Radio Shack.
