Transmission crossmember question
I have a 1987 V20(4wd, 3/4 ton) long-bed truck with a manual transmission, and after struggling for quite a while getting the motor mounts to line up, I realized the problem was a severely bent transmission crossmember. I think replacement will be the simplest option, and we do have a quite decent junkyard nearby with a lot of these older trucks.
What vehicles am I looking for to find a replacement? Is this crossmember the same as 1988 and up, or 1986 and down? Is the crossmember the same for manual vs. automatic? 4wd vs. 2wd? 3/4 ton vs. 1/2 ton? Any advice you can give will definitely be appreciated! |

Re: Transmission crossmember question
I believe it is 85-87 then 88-91 k5s suburbans I beleive the cross member is the same from auto or manual and no the 88up ck's have a wider frame. Also they are specific to 4wd as well and 1 tons are also shorter because the frame is taller
