i need some of those studs for the exhaust the 3/8 N/C to 5/16 N/F. do you have like 4 of them? or where can i get them?

 

I usually get mine at the better auto or marine speed shops but the last bunch I found on line at some hardware outlet . Only have a pair left or I'd set you up bro , sorry .

They are called step or stepped studs , heard it both ways . Good luck in the hunt you find some PM me I'm needing to re up the supply too .

That's the jewel but I like them a little longer 3/8-16 x 3/4 by 5/16-24 x 3/4 , usually run about $2 each . I also use the 5/16 12 point aircraft lock nuts on those studs , you can use a 3/8" boxend wrench on them for good torque and extra room to work with . Never had one back off with this combo .
