Transmission crossmember question

[kipps]

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!
