Which specific model are you looking for?
Auto or 4 speed or 3 speed?
I have one of Galen's white books that breaks them all down from engines, transmissions, and body style.
For example, I'll post Swinger 340 cars.
All of the V.I.N.s start with LM23H0R
13,781 total made.
10,382 sold in the U.S.A.
955 sold in the U.S.A. with a 3 speed manual on the floor.
4,423 sold in the U.S.A. with a 4 speed manual on the floor.
5,004 were automatics sold in the U.S.A. without a breakdown of column mounted or console shifted transmissions.
I hope this helps everyone...
