The 199 water pump should " fit, so that's not a big deal (remember, serpentine belt pumps run " backwards in relation to V-belt pumps). Mounting points for accessories " changed in 1974, so you will have to adjust/modify/fabricate brackets " to fit. " " 3. The biggest hurdle is the transmission. If you have an auto it can't " be used. The bolt pattern for the six changed in 1972 -- 1971 and " earlier have a smaller diameter bell. You can use an old model manual " trans by getting a 1979-83 bell housing. You'll need the 79-83 manual " trans bearing retainer too. there's a simpler way - an early '70s 3sp bell, '72-5 or so. the 3sp was a t14 with the same nose as the '68 t96. btw the t14 is also stronger and synchro 1st, and the t96 is marginal with 4.0 power.
