I just pulled the 5.3 4l60e out of my 37 ford coupe and want to put it into my 67 chevy pu with a 4l80e I am running into a problem with the converter to flywheel according to genstar transmission there is a stock gm flywheel that comes with a spacer and bolts to do this swap but no one at gm knows anything about it has anyone here heard about this or know the part no

Should be the standard flywheel package for a late model truck that has a 4l80e. I don't have the part numbers off hand, but a quick search in this section of the forum should get ya one real quick.

Ya, I think I remember reading that the kit is no longer available and you'd have to buy the parts separate. I bought mine used from a member here for my swap. A competent parts guy at a GM dealership should be able to find the part numbers.

the flexplate part number is 12621399
the spacer is part number 12563532

this use to be all in one kit for $60 now the flex plate is $6o and the spacer is $54 and dont know how much the bolts are
