do you guys know if the standard body mount bushings available for 1/2 ton trucks are the same as a big bolt. i am looking at the kits and i don't know if it is right. i can only see the rear cab mounts on my truck and they have a rubber donut shaped bushing between the cab and the mount and one below the mount. this is one link but i can't tell what's in the bag
