Where can I buy square headed nuts and original type of rivets for old restorations? I have to remove rusted panels that are riveted in. What kind of advise do you guys on panel replacement? Any photographs of skin panel replacement?
Google Big Flats Rivet. I don't know if Jim carries everything you need, but he may have advice if he doesn't
Restoration Supply has a lot of hardware to offer...
You can find them on the web.
Fastenal can get you square nuts,and RV Anderson carries many of the original style bolts.
