I've checked Discount Auto and Napa and neither have much of a selection. Is Pepboys any better or is there someplace else that has a good selection of quality metric exhaust studs. Also, wheres a good place to get 3" 3 bolt exhaust flanges and gaskets.? Thanks.

 

Try an exhaust shop. They are bound to have some of that shit laying around. If you can't find a stud just use standard bolt, nut, and washer combo.

You could also try Automotive Engineering for the collector flange/gaskets.

 

Any nut and bolt shop. Check the yellow pages.
