Hi, hoping someone will know how to fix this....I have a american autowire wiring system that came with this car I bought.....the car was a basket case but the car is a 1973 Firebird and it had NO rust from Texas. Everything with this car is messed up from people that didn't know what they are doing. I have been fixing the wiring in it and it was time to bolt the fuse box into the firewall...shocker the firewall was stripped...put new bigger bolts in....great. Went to screw the engine wiring block into the main fuseblock.....shocker....female part nut in the fuseblock is stripped.....these beauties over tightened the bolt....does anyone know how to fix this? Thank you.
