FAST 78&90mm bolt questions
Does anyone know the sizes of bolts or does anyone have an intake sitting around that wouldn't mind measuring some bolts for me so I can go to home depot or something and buy them? I also wouldn't mind buying the bolts from someone if by chance they had them laying around. Any help would be greatly appreciated thanks.
Unless you are talking about the internal bolts and screws which hold the shell, runners, base together. Those are going to be harder to track down.
The valley cover bolts are M8 x 30mm. They are button head cap screws aka button heat allen screws. If you can, I recommend stainless because they are under the intake where water can get can cause rusting. A very small amount of anti seize on them would be a good idea as well.
You will more than likely need to visit a bolt/screw store, I doubt Lowes or Home Depot will have everything you need.

I got all that in stainless socket head rather than hex head, and it cost about $18 at a local hardware store. I still need the longer manifold bolts that thread into the cylinder head as these only bolt the shell to the base and the throttle body to the flange. With the manifold painted black, I think the stainless will stand out nicely.
