I was working on taking cab off and found huge weld with a crack in it. Anyone every seen crack like this before?? Also on passenger side under radiator cross member rivet is gone. Frame rail moves with pry bar I think it will be easy fix.
I bought a 75 k20 it has a sbc turbo 350 203 transfer case. Did truck come with a k case turbo 350 with aluminium dust shield and brackets that go to engine mounts? Or was it an option when truck was new? Transmission right now just has sheet metal dust cover.
