actually I did notice in your previous post it is a 3500, I'm assuming I can order the stops for the overload springs, see what length bolts are recomended and find if the overloads are sold seperate from the assembly I already have. When the seller delivered my camper his 2500 wasn't squatted in the back, he has [jounce?] bumpers. I didn't remember to look under and see if
they were making contact.
the 84992005,6,7,8 i'm guessing are left and right of two different weight ratings. I'll crawl under my truck and check the numbers and see if they match side to side.
thanks for all your help, I'll be bothering you more later i'm sure.
