On my 68 C10 I ran my exhaust thru the stock TA crossmember. I bought a 2 pieces of 1/4" flat stock 5"? square. I hole sawed a 4" hole in both and welded them to the TA cross member.
Another thing to look out for is drive shaft clearance. My 68 was lowered 4/6. With my engine combo (LS6/T56) the drive shaft shop said I needed a 3" drive shaft. When I installed the the drive shaft it was close to the TA opening at the top. I cut away some of the opening and then I welded some 1/4" material to the top of the TA crossmember.
