I have 3 GM 3 speed trans for sale. First one came out of my 55 chevy and was in perfect working order, I replaced with a 4 speed $40 second one (long tailshaft) I know nothing about. It came with our 59 ElCamino and seller said it was in good working condition. $40 Third one (short tailshaft) came in our 59 ElCamino and worked fine for the short time it was in the car while we had it. I changed it out to a 4 speed. $40 Come get them, $40 each or all 3 for $100. PM me here or email me at [email protected] Thanks Gary
