Here are the correct original belts. The 582057 is early 62 and the 587000 is late 62 if I understand the parts book correct. Not sure what the difference is? I did not measure them. The 582057 is the original to our 4 speed 62 car. The 587000 was on the 62 engine I got from Ken but not sure it is original to that engine. The 587000 is at least in the parts book as a late 62.
