I do not think there is a GM registery. , i appreciate any help finding out more about 62 927 cars , i live in Australia and had many chevys over the years , 58 - 64 are my favorite , althought our local built chevys never offered many if any options , 58 and 59 were belairs 4 door only with a 6 cylinder and iron powerglide , 60 to 62 had a belair 4 door and impala 4 door pillarless with 283 and iron powerglide , 63 and 64 had 327 belair and impala 4 door and an alloy powerglide ( these transmissions were 2 inchs shorter than the 65 alloy powerglide and had a course spline rear shaft as well had a lower ratio low gear plus the pump ran off the prop shaft ) , back in the day ( like 20 years ago )American 2 door imports were very desirable but out of my price range , now i have finally bought a 62 927 impala ss coupe I'm tryi g to learn as much as i can about them , thanks for your help ..
