Be careful to make sure the bellhousing on the C4 is the right size. There are 157 tooth and 163 tooth flywheels. The bells have to match the size.So im picking up a 93 302 h.o. motor for the cougar to install up to a 73 c4 trans so my question if the 93 flexplate came from a c4 or aod will that bolt right up to the older c4 tranny??
