I am obtaining the parts for this and had a question. I currently have an E3ZR-6394-AA bellhousing and an E6ZR-7515 AA clutch fork to use in my 66 stang swap. If I understand correctly, anything 83 to 93 will work. If this is correct (is it?), then my bellhousing is an 1983 and the fork is an 1986 using an online decoder. Does anyone know of any differences in these and will they work together? Obviously the best choice is to get matched years (either bell or fork) but currently I don't have that luxury. Any advice?
