My '71 is all metal. The latch is solid as well, no issues there. Those who have them popping open should take a look at their latch and adjust it as needed.mikeconner1 wrote:I look forward to having one. Towards the end of the month I'm going just south of Chattanooga into N GA to pick up my new 8 foot bed, and it happens to have this option, so keep writing in on this thread, gives me some good ideas about what to stick in there. Are these things plastic or steel on the inside? The one in an old 78 F150 we had had a heavy duty ABS plastic liner, just curious if these in the old bumps were stamped steel or plastic. Reckon I'll find out soon enough. As the the doors popping open, might consider replacing that old paddle latch with the newer T-handle type that doesn't have that problem, much more secure. Had one of those old paddle latches on an under-bed box on one of my old rollbacks, lost a lot of tools on the road before I replaced it.
My box has jumper cables, a tire iron, an incomplete tool set, an incomplete 12V compressor, and some other junk my grandfather put in there about twenty years ago.
