Auto Trans

Hey Just A Que I Have A 51 Chevy Truck W/ 216 6
My Que Is What Auto Trans Can I Use To Bolt Up To That Engine.
I Want To Replace Manuel With Auto.
Will I Have Drive Shaft Problems .
What Year And Make Should I Be Looking For.
Any Info Will Help Thx.

 

2 speed powerglide or truck 4 speed hydramatic, either one from a 6 cyl. Mounting will take some work for the PG, as they never came in pickups. A hydro will be hard to find.
