What size bolt?

[Redog]

What size bolt goes in the bottom of the throttle body?

I was cleaning the engine bay and noticed a bolt missing No vacuum leaks (at least that I know of) but I would like to replace this bolt.

Does anybody know the size of this bolt. I have a top bolt, but it's a different size

i believe its either an 8mm or 10mm.

hit up a junkyard and take one from a GA or alero. stick it in your pocket, walk out...... hell its one bolt they might just give it to you for free.

should be M8-1.25 30-40mm, depending if you have stock or aftermarket TB

M8x1.25 x40mm long would be the one to use. you wouldn't want to only have 5mm of thread howing because it would strip out. ideally you want 2x the diameter of threads when you thread into aluminum.
