Is this possible for a 1981 g20 1ton? Seems to be the drive shaft is too small and the ubolt is on the wrong side of it. Thanks. | | | Re: Hello.

I have 4L80E in both of my G30 1 tons .... maybe a 4L60E would be good.
Again welcome
Question is it a G20 or a G30 .... G30 is a 1 ton a G20 is a 3/4 ton
