Mar-K,
I have a few other concerns. pictured is the bed to frame fastener. as you can see the fastener head is not much bigger than the hole through the cross sill. i feel like there should be a washer possibly? the welded cross sill washer seems to work fine.

second: the head on the bed to frame bolt will continue to spin if i keep tightening it, correct? there is nothing to actually hold the square (or common) head still while tightening the nuts.

third: i have 10 bed to frame fastener locations. 3 cross sills on the front half of the bed with bed to frame mount holes in the sills. then 2 on the back half, one removable sill, and the welded one. (i am 2 bed to frame bolts short, my kit included 8)

fourth: you recommend a rubber plate between the bed and frame (i assume this is for squeaking) What do you recommend an individual use? a rubber hard enough to stand the test of time and weight is probably going to be tough to come across. I looked at LMC truck's catalog but didn't see anything.
