I have 1 3/4" long tube Chevelle/A-body BBC headers on my 89 CC dually. They fit w/o issue. My frame rails are taller so the collector is above the lower lip on the frame rail. on a 1/2 ton rail they would likely hang slightly below the rail.

I also used 1 3/4" 'mid-length' 68-72 Chevelle BBC headers on my 67. I recall slightly trimming the pass side rail for clearance (not necessary but I wanted the same clearance on both sides).
