My buddy has a 1965 Mustang with a stock 289 and C4 transmission. The trans needs to be rebuilt or replaced. He found a TCI C4 with bell housing, torque converter and flex plate for sale locally that came out of a 70's F100 with a 302. Pretty sure his C4 has the 24 splines with the 157 tooth flex plate and the TCI has the 26 splines with the 164 tooth flex plate. Would he be able to use the TCI if purchased? I don't know crap about these types of transmissions. At the moment he's not looking to convert to a AOD or T5.
