If I were to have my seats redone in leather, and I would love to, I would not put that kind of money into them unless I could also get new seat "buns". My driver's seat is getting pretty thin (ouch!). They make them for classic cars like Camaros, but I don't know of any sources besides perhaps the Dreaded Dodge Dealer to get them for newer vehicles like ours. New springs may well be in order, too. Again, they are available aftermarket for classic cars. Ours?
I also need new hardware and cable and bezel for the automatic "tip-and-slide-forward" mechanism for my passenger seat in my extended cab.
