140 Manifold studs
I'm looking to replace my manifold studs but can't find anything long enough. Standard is 5/16" x 45mm(probably 1 3/4"), both sides UNC. Almost every stud I can find is UNC in the head, UNF outside.
I'd be happy enough to fit the UNC/UNF other than I need to remove the studs to remove the headers, which means double nutting them each time. I've got loads of 5/16" UNC nuts but UNF ones, less so. And I don't want to have to carry both lots of nuts in the spares case.
The ideal stud would probably be 2" with an allen key head so I can R&R the studs easier.
