1951 GMC TRUCK
 

I WANT TO KNOW WHAT KIND OR SIZE OF TRANS
WILL FIT THANK IT;S A 235 OR MIGHT BE 216 NOT SURE ALL SO NEED A MASTER CLYNDER AN
HAVE SPEAR WINDOW ONE ON THE SIDE CURVE

Any GM light truck trans from 48 and up and Chevy car tranmissions from 55 till the mid 80'3 will work.Some GM truck 4 spds after 1968 have a larger front bearing retainer.If you have a torque tube rear axle, you are pretty much gotta keep what came with the truck or change out the rear axle
