I was specifically hoping someone could tell me what would happen if I switched from the spring mounts to a solid mount. My concern is things are usually done for a reason and I'm afraid the springs are there because the frame flexes so much that a solid mount would result in the bolts tearing holes in the cab sheet metal.

Anyone? Anyone? Bueller?
