Mechanic mike yes the wheels now wheels are thicker. Think they are rated 4000lbs +
You may have a shortage of stud in your nut. I would guess mine at 3/16 maybe a little more. Got some longer studs coming appears they may have introduced these in 1973. Will post when i receive and install. We should have plenty of time here before I need the truck as the weather is uncooperative. Tom
