A-999 Swap and Information

Low gear sets can be found in lock-up 904 applications - Diplomats, Gran Furies etc., early to mid 80s. Those particular transmission are not desirable for performance applications though because of the lockup feature. Same as a regular 904 otherwise.

Look on the My Mopar trans guide reference to get the PK # number off the driver's side pan rail and then go get one. Bet you could find one laying in the dirt somewhere...
