Our first thought was urathane or solid cab mounts. Wait, do we need cab mounts? We unbolted the cab and set it down, it almost clears. Some parts of the floor hit the frame. Hmm, we carefully notched the floor and set it down. This is the first drop. 1 1/2" down. We carefully aligned the cab to the chassis and bolted the corners down, then welded the floor to the chassis. Yes, this may increase the road noise, it will also strengthen the truck as a whole. We're going for it.
