Another snag, looks like the 1955-59 clutch housings are the same, 60-62 and 63-67 and the 3 don't seem interchange. It looks like they all take the same starter and motor mounts etc. Anybody know just what the differences are and do I need to use my 56 that is in it all ready. I have a 1964 that I had planned on using, but it looks like possibly the clutch forks are different and the early fork won't work with the late housing?. So am I going to need to take it all apart after pull it out and use the early one? Had hoped to just pull one out and stick the new stuff in, in one easy operation. Currently a tired 283 w/3 speed and hacked up floor linkage and going to get a 350 w t5 trans . It looks like need to use the bent 56 clutch fork instead of the straight one used in 64. . All going into a 3100.
