Re: Drug home a 67-72 2x4x4 crossbreed.

My guess is it was a 4x4 po blew tranny tcase combo installed a 2x4 tranny

Many k20 trucks have a baseplate yoke design that the ujoint goes into a baseplate which gets bolted to the flat yolk on the front diff

You can look at front spring mounts to see if there factory rivited or bolted on

Laatly check your vin whether its a c code or k code truck
