72 C-20 Help
 

Evening Guys I have a 72,C20 350 engine on the passenger side the original exhaust manifold im missing the front 2 bolts can i get the size i need to replace them and are they fine thread,s or cource threads?? Thanks Saddletramp

I'm pretty sure that a 3/8'' coarse thread 1-3/4'' or 2-1/4'' long--sometimes a 1/4'' longer will work without bottoming in the hole. Check for this. Any brackets attached to this part of the manifold will require longer bolts

If you need two bolts and no stud end bolts I'll look tomorrow.
