Replacement Bolts

[MattBlur]

Anyone know if there is a one-stop-shop for replacement bolts?

Doing an intake manifold swap and most of the bolts were rusted/corroded and didn't end up making it through the tear down. I also need some of the minor bolts for the thermostat housing, fender connecting bolts, etc.

Or if anyone knows where I could find documentation on bolt sizes, etc.

Check East Coast Bolts or Dorman.....but, you need to know the size/thread of what you need. They carry the hardware, but no cross ref. as to size of a particular fitment.

lookie here: https://boltdepot.com/

I've used them a few times in the past for various projects around the house, and their inventory is vast, shipping is fast, and prices reasonable.
