4 speed manual transmission used in GM trucks through the sixties and early seventies. Prized by rock crawler builders because of its extremely low first gear. Advance Adapters offers products to convert older Jeeps & Willys to this tranny.

Comments: Love the swap to the sm420. Extra low granny gear that won't let you down and you can find one used for 80 bucks
