First off I'd like to thank the brain trust that this forum represents. This is my first post but I already have gained An incredible amount of knowledge by reading and searching here. I have a 74 Glacier. Noticed the floors creaked when walking, so took a look underneath when I had to pull the tanks due to internal rust. It has full length isolator pads on the frame rails still in amazingly good shape and pads at each cross member of the ladder frame. The floor bows up in the center so it is 3/8 to 1/2" above the pads in the center, with the worst one being the one forward of the door. My first thought is to pull the floor down with carriage bolts through a fender washer/ the floor/ the existing pad/ the crossmember/ another rubber pad/ another fender washer. I'm thinking 3 or 4 at each crossmember and pull down evenly. I think the second pad under crossmember will isolate well enough and the fender washers should spread the load on the floor. As a secondary measure if needed I am thinking of bolting a set of rails and brackets to the outside of the frame rails to support the aluminum closer to where the load from the sidewall comes down. I would use the existing frame crossmember bolt holes as anchor points.Don't want to do this and don't think it necessary. Just trying to anticipate any point load/ fatigue problems. Anybody have experience with this or another approach/ improvement?
