Gentlemen, gentlemen, please, I'm blushing No no I've no experience with m8s - both the m6s for my snail fan are still in situ. Qualified rivnutter - tick
I think rivnuts are risky anywhere that's likely to corode. My only experience of rivnuts, oft repeated, is bolt rusted into rivnut, rivnut spinning, no access yo the other side. Nightmare.* *I might be repeating myself, soz if I'm getting boring but I wouldn't have a rivnut on my van.
But it's not a problem if you use stainless rivnuts and bolts. The spinning is caused by duff installation I'd say.
Might go for the slide hammer, as I've broken it anyway. Was well lubed up with Copaslip, but the thing has welded itself into the jacking point.
No, sir. While the sun’s out and I have a (minimal) level of enthusiasm, I want to clean up everything under the load floor. The step bracket’s been jammed in the jacking point for years. Time it came out...
