Just put a set of buckets in my el camino. After putting them in I noticed I will have to get the seat belt holders that attatches to the headrest. Problem is, when removing the bolts in one of the headrest I saw that somebody must have stripped them out and put some huge 3/8 if not bigger lag bolts in the holes. Now I was wondering if anybody had attempted to repair these? Not sure if its metal or plastic but I was thinking about removing the headrest and either welding the holes or epoxy them and then rethread. Unless there is something anybody else recomends?
