Frustrating work.... broke one of the click bond studs...not sure how. Broke about in half. Ended up having to rethread remaining stud with 10-32 NF die..had just enough left to get nut on. On the click bond on the firewall above the fuel pump the whole stud came off!! Guess I didn't prep it well enough...was hard to reach. Re-did with 10-32 rivnuts
