914World.com _ 914World Garage _ Speaking of engine tin: Fasteners?

Re. this thread, http://www.914world.com/bbs2/index.php?showtopic=214419

which reminded me I have a job on my car still unfinished - Engine compartment tin: Does anybody have a source for 'captive' nuts/fasteners, such as you see on the stock tin?

I have some big gaps in the enclosure around my motor, a 3.6 conversion, which I expect won't accept any stock 914-6 tin. I had planned on doing hand mockup/fab of the needed parts to close it out. The final detail being, how to tie them all together, with minimal 'craft work' involved.

Screws are easy to come up with, but what about the nut side. Captive being the most important feature of these of course... The captive nuts I've seen on VW tin appear to self-attach via square-punched holes in the metal. While such parts might be found w/o too much trouble, I think the mounting holes would be hard to duplicate without a lot of hand labor.

If anyone can point me to a decent source for fasteners to do this job or a good alternative solution, I'd appreciate it!

The nuts on 914 and 911 tin are, for the most part, square pieces spot welded to the tin. The only exception being maybe the captive nuts that are incorporated into the oil cooler.

What about a rivnut? Picture a rivit with a nut inside. They can be installed either by power or manually
