The transmission is OA139303 and #99129HA3 any info on these numbers? I'm guessing it's 18 spline out of a 70 b-body?

Thanks Mike



OA139303 is the last 6 digits of the 1970 B body that transmission came from.

0 = 1970

A= Lynch rd. assembly plant, they only built Satellite and Coronet B bodies there B bodies there.

139303 is the VIN sequence.

99129HA3 I'm pretty sure that is the casting number on the maincase , basically a useless number.

running up my post count some more .
