Trying to take the heater box out of my '88 MJ and the studs that go through the Firewall are spinning with the nut. Thats not the problem, althought it is, but I'm looking for a fix to replace those studs once the box is out and ready to put back in. I have an idea of drilling out stud locations and using long screws or thread all with JB Weld to replace the trashed studs. Has anyone ran into this problem and if so, any words of advice someone might be able to pass along? Thanks
