what thread is the TBI to manifold bolts?
what thread is the TBI to manifold bolts? im making a TBI to carb manifold adapter and i need to buy a tap..
i dont really want to try to take one of the bolts out of my car on the off chance that it makes the TBI gasket leak... so if anyone knows the thread, please post.
(and yea i know the PAW ones are only $12, but ive been meaning to make one for the past year, so im just doing it.)
