[6869704X4]

Wonder if the frame is bent. My 70 shortbed is approx 291/2 in. between those points.
Its hard to tell because this where the 4x4 and 4x2 frames differ. Best I can remember the 4x2 frames are parallel through here. The 4x4 frames are narrower where the engine mounts, then spread out. By the time it gets to the rear shackle mounts it should be parallel all the way back.
Hope this helps.

Edited for clarity, I hope.
