So I've seen the list on here of the torsion bar codes. http://www.gmfullsize.com/tech/torsion401.html
But those are the rpo codes for them. Does anybody have a list of the actual numbers and casting codes in the end of the bars and how they correspond to the rpo letters. I have a set of bars in my truck now that is sagging, and trying to figure out if the bars I found to replace them are stronger or lighter than what I have now, before I put them in and try them.
Ps. My factory RPO codes say 6YH and 7YH
