New Guy With An Old Duster

Looks like maybe a voltage regulator or some kind of regulator also for the AC?

That's a logical guess for voltage regulator, but I've already purchased the replacement for that and it wasn't either of those parts. As for AC related, the car has no AC. For that matter it has no power brakes or power steering. When you lift the hood on this one there's nothing in there but the engine, which is just the way I like it. Most of the pollution control stuff disappeared in 82 when I had a muffler shop install headers, and the few odds and ends that remain no longer serve any purpose, having essentially been along for the ride ever since.

Anyways why haven't you tossed a $25 timing chain and gears on and a cheap set of push rods and fire that baby up!?.

I probably should've done that back when the engine first died, but at the time I feared damage to the valves and wanted to pull the heads to inspect them. Unfortunately four of the head bolts on the drivers side were blocked by the headers and the headers couldn't be pulled clear because of interference by the steering column. The muffler shop said they had to lift the engine to get the header in on that side. As a result of the trouble they've caused the headers will be coming off and won't be going back on, though I may look into a set of shorties. But truthfully I'm seriously considering hooking the dual exhausts up to stock cast iron manifolds. At this point after sitting partially disassembled for so long I really need to go through this engine to clear out any debris that may have found it's way inside. It's frustrating when I think of how easily this could have been dealt with thirty years ago, but I wasn't a mechanic then and didn't have a clear picture of what I was up against.:(
