Looked through my catalog and web site but I can't find a black rear seat belt kit. Y'all have the front kits and say y'all have the back then I click and they only have 87-89 rear kits I have a 90 gt hatch. And need the rear. Especially if I put a car seat back there. And do the new belts lock like the new ones do. If you pull the all the way out and let them go back half way do they lock or will I still need some sort of belt locker. My 3 yr old wants to ride but I can't get belt to lock so car seat will stay in place. Ideas? Will new belts lock? Do I just need to call in?
