1979 k20 front drive shaft
« on: December 07, 2022, 03:04:14 PM »
Does anyone know if the front drive shaft off a 1986 half ton suburban will fit on my 1979 k20 truck

Do they have the same transmission and xfer case?

If they are the same, I don't think the distance between the case and diff would be different.

BUT, I have known to be wrong... 8)

Just looked, they have the same u-joints, 1/2 ton to 3/4.
