I’m stumped. On my 87’ K10 rear cab mount / crossmember it has that extra bracing that I thought only were on K30’s. I’m pretty sure they are not interchangeable due to frame rail size differences.

Any insight into factory K10’s with the crossmember bracing? Can I replace with a standard crossmember w/o the bracing?

Pics are of my (filthy) frame and a representative k30 frame for reference.

Maybe the truck was rebuilt with a different K30 frame years ago.
