I would PM the known owners - or ask Bob to give you a lead.
I really can't be of much help 'cause my 428 car had no radiator, engine, trans or drive shaft. But,I went with a Shelby friend for help and found that some part #'s, proper for me, were started w/ C6, C7, and/or C8, pulleys included. Also, my biggest concern, too, was PART #s like on the block(and the "C" on the end of the block), heads, intake and exhaust manifolds, carb, distributor, starter, alternator, radiator, water pump, fan blade and clutch fan to name a few, plus the Kevin Marti engine bay hoses, belts etc. AT FIRST, I was not really all that concerned with dates particularly, but did try AND DID FIND PARTS that predated my car's build date. SO, PATIENCE WAS A VIRTUE and I think that I covered most of the bases quite well. Thanks to Scott Fuller, I found that I had the proper exhaust and rolled tips still on the car (getting noisy now but I love it). HC Bob here.
