I wanted to attach my scuttle with rivnuts. Mostly because that I will want to remove it again in the future. But rivnuts leave the scuttle sitting 1.5mm off the chassis. I know you can get low profile ones but they still leave a gap. What did you guys do? do you think it possible to use some sort of rubber strips or trim?
Countersunk rivnuts. Zero profile
You could use rubber trim to fill the gap, oryou could make the fixing holes you drill in the scuttle larger than the diameter of the rivnut and then
use a strip ofmetal as a load spreading washer. That way the scuttle will fit without a gap.

drill the hole out larger on the scuttle so it sits over the rivnut then use a large washer with the bolt. Alternatively use blind rivnuts (think this is a name for them)

What are you using for the side panels on the car, fibreglass or ally as it will have a thickness similar or more then some rivnuts.

Yep that is what I meant and did on mine. Used countersunk rivets to fasten the panel on with.

Rubber trim on mine
Where did you get the trim from?
Rubber 'P' trim on mine from woolies trim in deeping near peterborough they do allsorts
Used Ali side panels folded over means they end up flush...
You could use rubber strip, or P section rubber strip. Depends on how the panel gaps look as well, the rubber P strips can hide such problems!

Rather than drilling the holes in the scuttle too big right through cant you just countersink the underside? That way the protruding rivnut will sit
in the countersink but you won't have holes that are too big for the screws.

I used rivstuds, large hole in scuttle, rectangular plate over hole and serrated flange nuts.
i'm drilling a hole in the chassis, inserting a threaded insert, curving the steel around the hole to make more space for the weld (centre punch
and hammer) welding the threaded insert in place, grinding flat.
more work but permanent and no risk of it slipping or water ingress into the chassis rail.
edited to add - or welding the threaded insert at the side of the chassis and making a large lipped washer to go over onto the GRP.

The Fibreglass side panels made mine flush in the end. Think it'll be pretty similar for ally ones!
