Yesterday, I did a tune up by replacing all of the spark plugs, wires, and valve cover gaskets. I lost a few bolts, and I have no idea where. So, I need to find two bolts for the timing cover in the rear, a nut on the side of the intake manifold, and some for the air intake. The only problem is every oem part site I try to buy them from do not sell the bolts. How do I get them. I don't want to drive the car until I get them. The car runs fine, I think. It's just a little high rev about 1000 rpms. It's an 00 Eclipse GT.

Edit: I tried driving it and it had absolutely no power at all and the car just shook. I took at the front three spark plugs and they look fine. I hate to have to take the manifold off again and deal with the rear three.
