Don't worry Glenn, I'm the ONLY stud she can handle LMAO!!!! Talking with my motor machine shop owner yersterday, he was stating that likely an A460 head stud would work(it's 9/16"), but not sure lenghts yet. Mack part calls for 6 3/4" Just talked with R&R Mack, Jeff did some soul searching and came up with a pair of part numbers. One for $10, the other was $44? WTH? The cheap one was for 36 bolts, the other was 32 bolts. Mine has all 9/16, so we're thinking it would be the cheap one. The 32 count would likely be for the bigger 5/8" in the corners. He also has my axle seal in stock(ouch, $167). Mike, I'll confirm part number and let you know the damage. Not sure if you want all of them? Likely not enough around, as he checked parts availability and only few here/there in system. Might need to look into ARP if you want all? ($44x32= $1496 yowza, where 36x$10=$360) BTW, on the air ride. I was able to weld and grind the rear crossbeam pins and get that fixed up last winter. I was able to get the front arm bushings out pretty easy. The RF was toast and that was the reason for the looseness. I was able to just torch the rubber out and cleaned the hole with a cup wheel on air motor. I then used the long mount bolt to install the new bushings. Was pretty simple actually. Couple big washers, some never seize and lube for the bushing. Couple seconds with 3/4" impact and the bushings were in. All in all, it rides better. The bad shake is gone. I then readjusted the toe-in and that helped with the shake in the steering wheel. Still not 100% perfect, but much, much better.
