well the rivet nuts were a COMPLETE FAILURE!! Now i got a mess from hell. Dont see how they are of any use. I installed the damn things and went to tighten the bolts up when mounting the ECU and the stupid rivet nuts turned! They refuse to grip the sheet metal enough to tighten much at all. I had to grab them with a pair of dykes and rip them out of the firewall. Now i am screwed.




That sucks , there are better choices than the one you ended up using , but I'm sure that was all you could find in a local hardware store , but you should have drilled it out and not ripped it out , but I understand the frustration.

What does the firewall look like now ?
