My 2004 wrangler sport front passenger seat belt recently started to fail to retract. The driver's side has been that way for a while. Apparently, the plastic spools inside the recoil assembly's that the webbings roll up on are crumbling. My plan was to replace both sides. When I did an internet search, I found a few outer oem assemblies that turned up at $500-600 per side. Apparently, Jeep decided to discontinue them. I really didn't want to have to go with aftermarket belts assemblies. Anyone have any luck with later model belts if you changed out both inside and outsides? Thanks
