I have a 1966 Impala SuperSport with a 327 and it is suppose to have a 2-speed powerglide in it, but it has a 3-speed. I want to put a powerglide back in. I bought a powerglide off E-bay the guy said it came out of a 1966 chevy. I found some numbers on it, on the shaft the number is 3863192, and on the pan is C7E02D. I need to know if I can use this with my 1966 327?
