67 Short wide cab mounts

[partsman3]

I took this truck down to the frame. After blasting and painting the frame and preping the cab and bed it's all going back together. The new cab mounts have the cab sitting a 1/2 to 3/4 inch lower than the bed. I got the mounts from Classic ind. I went back to the cataqlog and they list a set for 67-72 1/2 ton 2WD. I also found a set in their catalog for W/ wood floor bed. Turns out that is the set I have, with wood floor, but my floor is steel. I looked at other sources and they all only list 1 set. Has anyone seen this??
