Thanks, will do. Problem is figuring out exactly what year PO cobbled parts together. Truck is a '56 on an early '70s truck frame, with some Chevelle running gear. I've upgraded the steering, redid the interior including gauges, did some re-wiring, and just swapped the TH350 for a 4-speed, with mechanical clutch linkage. Got immersed in the ignition switch when I put a new CVR starter in place of the old GM unit that wouldn't clear the new 621 bellhousing. When I bought the truck some years ago, a friend told me I should immediately rewire the whole thing. Nah, I said, I'll do it in sections. Bad decision!
