1976 Crewcab Shortbed, bed is too low!

[RADustin]

Greetings,

I dropped the body on my project '76 this past week/weekend and the bed is too low as compared to the cab. It's about 1/2" too low on passenger side and 5/8" too low on drivers.

Some specs of my build-

• 1976 Crewcab Cab
• 1977 CCLB frame, cut to shortbed
• I assume late 70s bed floor, aftermarket bedsides
• LMC PN 30-1161 Body Mount kit (73-80 crewcab), tightened up till the pieces bottom out. Further tightening won't suck the body down anymore.

The bed is sitting directly on the frame. I assume this is how it is supposed to go. Bed fits fine.

From my measurements so far the cab is level with frame, but I will continue to measure different ways to confirm or rebuke. All 6 of the cab mounts have pressure on them, so things 'look' correct. I have the square shims on the front two body mounts, 1 on each side. The 4 rear mounts are body on rubber, no shims.

The frame is straight. I measured it out well when I cut it to a shortbed. The bed to cab gap is uniform top to bottom.

Anyone have some ideas? I can understand the bed being high, and cab low- but not the bed being low. I really don't want a body lift, uneven at that to make things right. I'm hopeful there is a detail I am missing.

Thanks.
