Help with old Part Number!
 

Does anyone have an old (really old) ATI catalog? I'm talking probably 70s or early 80s.
I have a planetary gear set (not an assembly) and I would like to know exactly what it is if that's possible. Doing the math, I'm coming up with just under a 1.96. I have seen 1.96 sets for 8 cyl. planetarys but this is a 6 cyl. set.
Any help would be appreciated, Billy.
The PN on the package is #20498.

The part # you have (20498) is showing a straight cut gear kit (2.08 ratio).There is also a 1.94 kit,but the part # is 20495.And also a 1.98 kit part # 20496.Catalogue is from 87. gsa612
