I moved halfway through my build and can't find a single one of them... I think I have the nuts for the exhaust manifold, but no idea where the studs are.

 

You can pick up the studs at the local Ace Hardware, or you can order them new from Finish Line Performance. I generally just call up Steve@PanicMotorsports and get him to ship me out the random nuts and bolts I need. There are probably a few companies on the west coast who part out miatas that will probably have spares of them all.

 

You can also buy them new from a Mazda dealer for like a dollar more than a used part miata place. But yeah steve at pannic is the **** lars taught me how to sex with him
