Did you or did you not take the stud with you....
Just do that...
Like I said....

I would make them thicker than the picture of that HKS manifold. I have seen thin cuts fuse back together over time

i dont have the studs i have the original bolts

the mani didnt come with studs?

nope it came with some bolts

so take the bolts and match the thread...

Uh..
Am I not saying something right?
If im not, sorry, but, just take them there and find some matchings, like koto said..

In the nuts and bolts section they'll have a bin labeled "automotive studs." Those are what you wanted. Dont worry about the class/grade, just get the correct size. Don't ask for help in stores like that, you'll get help from 90 year old men on their last breath who don't even know their piss from apple juice.

so i went to both the ace hardwares today and found the bin with auto studs yep sure didnt have the right sizes they were way to long and they only had like 5 diff ones

and the wrong thread pitch at that

your obviously not looking in the right spot. Did you tell them its for an exhaust mani for a miata. I know the ace down here, its divided between foreign and domestic Hehe.

yea they were like M8x1.00 and M6 M10 but not M8x1.25

I just picked this one up, are those cuts what your referring to?
