Hey Guys...Please help me identify this cross member, (the one under the back of the cab.) I would like to fit one to my kids 87 Trazer and use it to mount the back of the cab. Sorry for the horrible picture. It's all I got. Thanks for all your help in advance! The frame pictured is a 74 K5 Blazer. My kids frame is an 84 ish K5 Blazer, and doesn't have the crossmember. I was thinking it was aftermarket? It has two large holes in it that look like they would accept a body mount, although they dont line up on the 63 pictured. Thanks again! Kevin

 

As far as I know that is not a piece off a K5 frame.

Looks easy enough to duplicate for a cab mount.

 

you could always make one.
