Box to frame, rubber strips?

[firebird]

Pulled my box, stripped and painted my frame,new fuel tank and sending unit, cleaned up some wiring. Anyways I'm ready to put box back on, is there any rubber between the box and frame? There was nothing there when I pulled it off but I know the PO had the box off at some point.

Edit- was going to cut some inner tube strips up. Truck won't see any winter so I'm not to worried about salt and corrosion.

I don't think there were rubber strips of any kind. There's not full contact along the frame anyway, basically just where the floor supports cross the frame rails.

Both of my 74's and my 80 donor don't have any anywhere.

I was going to cut a square and a hole out of inner tube for each mounting spot but I'm not going to bother if there never was anything. I've seen plastic wear strips under mounting locations before on farm machinery it just had me thinking.

No - no rubber between the box and frame from the factory.

(I installed - well... my guys installed - about 900,000 pickup boxes).

There is a good reason for keeping the underside of the bed floor and the frame rails in direct contact - the rear lights:

The ground path from the rear lighting groups - back up to the battery negative - goes through the black leads in the harness, into the quarter panels, across the bed floor and then down into the frame at the bed mounting bolts. If the bolts should start to develop resistance, having metal to metal contact at the bed/frame surfaces will help maintain continuity.
