So the shell I bought didn't have it's seats bolted in, and all 8 of the seat bolts are missing. I called the dealership and they want like 15 bucks a bolt, and say that it'll take them a couple weeks to bring them in. I know you can buy them online for about 5 bucks each, but I'm sure you can just use a standard metric bolt of some size....

Does anyone know this size? The car doesn't run, so I can't take it to the Home Depot to try out diff bolts. I want to put the seats in it to complete the interior.

P.S. Its a 93 Fd US spec.

 

The bolts are metric and I'm guessing that the pitch it 1.5mm are they are probably 10mm or so. They are also likely grade 8.8 or better. HD's metric selection is very poor and they may not have high enough grade bolts.

I would order OEM.

Never call your local Mazda dealer - call Ray at Malloy Mazda (search for number).
