Shawn, did you pull that info from the 2g FWD bolt guide?

The fuel rail bolts sound correct - CAPS shows 8x6 (8mm by 6x length). The program doesn't show thread pitch.

Which motor mount bolts are you looking for? The ones that go through the mount itself or some of the other ones?

Actually i did thanks for asking b/c i thought it was for the 1g awd. Just have it saved under bolt sizes. I know i have one here some were just cant locate it. But im 99% sure the fuel rail bolts are the same. Not quite sure on the motor mounts.

Nuts and bolts are sized by the diameter of the shaft, length, and thread pitch like Shawn said.
While we may refer to the size of the head when we are working on the car that's not how you buy them.

Thanks for the reply everyone, I am looking for the bolts that go through the rear/front mounts.... Are the 2g bolts in the wizard the same?

Rear motor mount bolt - 10x?x110 - MU101017
Front motor mount bolt - 10x?x75 - MF140473

My guess is they both have a 1.25 thread pitch (when comparing them to the 2g bolts), but I'm not positive. I also included the part numbers if you want to order them from a dealership.
