Bed jacks into cab while off-roading

[Lugnutt]

I gota think this must happen to most trucks of this type (72 short step-side bed 4x4). Since brand new, my truck bed bolts have mashed into the cab every time the frame torques while off-road. I'm ready to do some serious body & paint work now and wouldn't like to start the mashing all over again with new paint. Anybody found a good work-around for this problem?

Thanks

Box the frame, add more bracing to the frame or build a roll cage to tie it all together. Boxing the frame will help, but wont stop the flex completely. Same for adding more cross members. A well built cage would put an end to it.

Some of it is probably coming from the rubber mounts under the cab too. The bed is "fairly" solidly mounted, but that cab can move around quite a bit. New rubber isolators would stiffen it up some, urethane is even more solid, but some guys say that the on-road ride is harsher than they like.

Button head cap screws will give you a little more room. They are low and mushroom shaped, so they dont hit as easily. I also slid my bed as far as it would go in the bolt holes.
