I'm looking for three specific bolts for 1995 Mazda B-3000 4X4 ExCab

1. The center bolt holding the spare tire. (Has loop on top)
2. The bolt that holds the spare tire cradle in place.
3. The lower rear shock bolt.

How do i find and /or describe these bolts? Would I buy them from a car parts store, a ford dealer? How do i find their exact description?

Thanks for any help.
