Did the seatbelt mod when I had them removed during the body lift. They actually work alot better now. The passenger side was tricky as the autobrake mechanism is different. I had to drill a small hole in the plastic housing and hold the stop tab down to allow the cam to pass when tightening the spring. This will make sense if you try the mod. I also soaked the belts in soapy water for a day to clean them up, as I could not remove the drivers side from the mechanism due to the small slot. I definately recommend this mod. Its a lot cheaper then replacing the belts.
