I just dropped the hammer on a set of the stainless lugs from PFP. Had to replace accelerator roll shaft, lugs weren't totally shot yet but close enough I figured I just as well pound a new set in while I was there. As mentioned in this thread they are same price as the ploy ones from PFP. I called Gibson and would have maybe tried a set of theirs but getting them shipped wasn't going to happen right away, they were more money than the SS ones from PFP but not much more so I just done the SS. PFP said they didn't know how long they would last, never had a set worn out yet to know.
