where to find a camshaft bearing stud?

[feltzo]

So i've got my 1975 CB750F big bore project engine mostly put together, and lo and behold, my crappy torque wrench snaps a camshaft bearing holder stud. Gall darnit.

Does anyone know where I can find one? I've got the broken stud out and I notice there is different sized threads on each end of it (which is normal right?), so the local parts stores for sure do not have an equivalent.

I've tried bikebandit.com and googling it and can't find a place online that has them in stock.

And I know an exact replacement stud would be preferable, but has anyone tried just putting a regular bolt in there instead? Seems like it'd be okay to me, but then again, I'm an idiot lol.

And one last thing, when and if i get a replacement stud do i just screw it into the head as tight as I can by hand, and then put the camshaft holder on with the nut and washer and torque it? Thank you so much guys, this site has been a huge resource for me throughout my various screwups.
