So as the title states, I am trying to fix my roof rack and can not find a proper replacement for the ones i have taken out. The writing on the top of the well nuts was painted over when the car was with her previous owner and a couple of them were different diameter heads with course threading versus the original fine threaded ones. Just wondering if someone would be able to point me in the right direction of where I could find a new set with hardware to go along with it. Picture soon to follow.

The special nut is listed as 14002811 and the screw listed as M4.2 x 1.4 x 20 part number either 11504477 or 11504659. You should be able to chase the screws down at a decent hardware store. McMaster-Carr maybe. Good luck and let me know if you need more part numbers to help!

Check your local Lowe’s home improvement store. I’ve gotten some there, but haven’t had a chance to check them out, and se if they fit.

Thanks a bunch! I'm doing some hunting on McMaster right now to try and get matching screws for the expansion nuts they have. I can only seem to find nuts for 1/2" holes in a course threaded option so the screws are being the pain in the *ss to match up. I need a copy of that book you've got hahah

I got the hardware book titled "Standard Parts Catalog" on the big auction site. I think I paid $20 or something a few years back. It covers all GM and GMC series vehicles including trucks. Everything from lamps, screws, nuts, bolts, studs, paint codes, cautionary labels, exhaust emissions tune up labels and more. Mine has a publication date of April 1988. So if the 'green pages' in the parts catalog doesn't show a part number, then you take the group number (in your case 8.977) over to the standard parts catalog and look it up in it. Most times I find what I need but it is not fool proof. I still have to take a run down to my local GM parts dealer for help once in a while. But I drive in with the '84 Cutlass and everyone is all smiles to help.
