bed cock-eyed from cab?

[ProStreet83C10]

does anyone have any issues with their beds sitting cock-eyed from their cabs? i know my bed has about a 1" gap between the cab and bed on one side and about a 2.5-3" gap on the other side. The other thing ive noticed is that it appears that at some point before i bought it someone had cut the frame right behind the cab and patched it with some steel plates which now cause my truck to not be able to use all the bed bolts. At some point after it warms up outside ill have to try and get some pictures of what im talking about and do a vid to show you guys how easily my bed moves around on the frame, really kind of a screwy situation.

Let me know if this cock-eyed bed is somewhat of a common situation or not.
