Replacement Alternator Bolts? - 90 Formula TBI w/ Serpentine

Hello! Does anyone sell replacement torx or hex bolts for the alternator on a 90 Firebird Formula w/ TBI and serpentine set up? I managed to mangle the hell out of the head of one of the torx bolts because it was frozen in place.

Thanks!
David

Any hardware store or Lowes or Home Depot will have it.

If you seek a factory fastener, you might also check with some of the people parting cars in our For Sale forum.

GENERAL MOTORS (auveco.com) I found these guys as a good source for OEM fasteners.
As mentioned your local hardware store may have a suitable replacement, take the old bolt with you and you should be able to match it to a hex headed bolt, typically automotive hardware is either grade 8 for standard hardware and 10.9 for metric, those are the grades you should shoot for but a lower grade like a grade 5 or 8.8 should work as well

Thanks for the info! Grabbed one at the hardware store and will be slathering it with anti-seize before it goes back in this time!
