In reading in the service manual, it speaks of how there is a thin shim or anti squeak material between the body and frame and that hold down bolts should be checked on a regular basis to eliminate squeaks due to lose bolts.
My question is didn't any of these mounting bolts have a spring under the nut so as the frame underwent twisting motion it didn't tear the body apart? I'm thinking specifically of my truck cab. Only bolted down in 4 points it seems like it would make some sense to have the front two bolts down solid being that the bolts go through the wood sill, but the back two metal plates that are just screwed to the main sills and rear cross sill, with some good stiff springs under the nut to allow for some forgiveness. Not that I plan on driving it down a railroad track or anything. I'm thinking for my 901 box I'm recreating also, having at least some of the 6 bolts spring loaded if you will to reduce on wear and tear.
Thanks
David

Hello David, In my opinion you are over thinking this, and going down the wrong path. If you leave those bolts loose by having a spring under the mounts how long do you suppose those bolts would last. Essentially all of the parts would be wearing at the edge of those bolts and the holes they are mounted through. Everything will get sloppy very fast. At that point it would not be "if it fails, but when it fails". It would probably be when it has the most weight, or people in it. Not a good idea, it needs quite a lot of friction to keep everything together. You want all of those bolts tight.

I see your point Art on the wearing. I was just thinking along the lines of some later year truck mounts I think I have seen on other posts (34ish maybe) thought they had a through bolt with a spring on underside of rail with a nut and a cotter pin to keep the nut from backing down.
And then also thinking along the lines of even newer than that where there is a rubber mount top and bottom of the frame rail snugged down with bolt and lock nut setup.
There must be at least an 1/8in thick or so rubber pad between the mounting and frame?

Maybe I am over thinking it for my grumpy old 28.
