Please post those pictures again ?I wanted to use the cruiser clutch so made an adapter to go between 1uz and cruiser bell housing. The 3B engine that came out of the truck has a plate that goes between the engine and bell housing with a hole that just lets the crank poke through, the 1uz has a plate about 4 inches wide that sand wedge the flexi plate to the crank. I put this plate in a lath and turned it down to the same size as the hole in the cruiser plate. Then I could put the cruiser plate on the 1uz and drill out 1uz holes giving a pattern to make adapter that would be with in a few thou.
I will get photos in the next day or so to help explane.
