Trans swap is 68 suburban
 

I have a 68 suburban C-10, factory 3 speed manual trans. I want to replace the 3 speed manual with a 350 turbo trans.

Does anybody know rather I need a short or long tail trans for the replacement, also do I need to replace the yoak on the drive shaft or will the factory original shaft work.

Your help is apreciated.

A short tail 350 will swap in and can use the existing driveshaft as is.

Yes, the splines are the same.

JimKshortstep4x4 called it right the only thing you need to change is the transmission, trans. linkage & transmission crossmember.
We carry a new style automatic trans crossmember here if interested

and a rad with a cooler, linkages and linkage mounts, a column or an aftermarket shifter

Ya I forgot about the trans cooler, Im figuring on a Ididit colum, don't want a floor shifter. I was looking at a trans crossmember from classic performance.
I don't know If i will change radiators or run a external cooler.

Do an external cooler, they're much better at cooling the tranny than one in the radiator.
