I have 1963 galaxie 289 500 xl convertible with FX trans that's out of service. Quotes of $1200 to repair, "if" it can be done due to lack of parts. Found someone willing to sell me a C4 with 5 bolt bellhousing for $600. Can this swap be done without too much trouble? Or look for different trans. The 5 bolt 289 bellhouse is a lot of trouble I've discovered. Thanks Tom
