I just hauled home a 72 duster project, got a sb 904 in the deal. car is a stick car so the AT is for sale, $100. i also got a v8 k frame in the deal i won't neeed, ..... but look up schumacker's conversion engine brackets. that is the easiest route.changing to larger t bars is good idea if street driven. yes you will need a 8 3/4 or 8 1/4 rear for the v8.
