CFR Firewall Shifter Bushing, Fasteners Options

[TargaToy]

I'm installing Chris Foley's firewall bushing which is a beautiful design.

Has anybody installed one using fasteners other than the sheet metal screws or pop rivets that came with the kit?

I've been contemplating installing #10-24 riv-nuts after reading someone else's experience with either the screws or the rivets (I can't remember which) working loose over time.

What's your experience?

Got me thinking...

That washer is ALMOST thick enough to hold threads as-is.

Here's a way to make it work.

New washer, drill and tap for 6X1. Need to be accurate, drill press and "technical vise" would help BIGTIME.

I'm betting you know this already.

Thread studs through washer and add nuts. Set stud installation depth and tighten nuts against washer. You just LOCKED the stud into the washer.
After checking alignment against the CF Bushing pack I'd loosen, add red Loctite, retighten.

That's a permanent solution in my book.

You can find 12 point 6X1 nuts to maintain style...

I just searched a bit and found Ti 12 points that would retain the coolness of the hardware.

External ONLY! The internal nuts should be cheapies...

I'd look at 5 X.8 versus 6mm stuff. I'd have to play around with it.
6 seems big to me for this application.
