With regard to the Saginaw trans swap. The center hole in your 60 bellhousing is a little under 5" which is standard for most of the early transmissions. The later Saginaw's (about 69 & up) have a larger front bearing retainer and use a bellhousing that has a hole that is a little over 5". Just a heads up so you don't end up with something that requires more parts & modifications. Fred
