Hello,
1st time builder and encountering one adventure after the other.
I am in the process of tearing down a 78 special. I was taking the exhaust headers off, and, 3 of the studs were 10x1.25, while 1 stud was 12x1.25. The 12MM stud looked realatively new compared to the others, which are rust encrusted.
It looks like the PO must of broken the original stud and replaced it with a 12MM, then, drilled out the mating exhaust flange. The edge distance on the stud to the cylinder looks good as does the edge distance on the flange.
So, I have a couple of questions that I'm hoping some more experienced builders can answer.
1. Is this a common and accpeted repair method?
2. Is there a 12 x 10 stud available, so, I would have a 12 mm hole and a 10mm stud, and the flange would not need to be drilled and the nut would be the same as the other 3?
3. Is it worth changing, given the risk of really screwing things up, or, should I forget about it and move on?
Thanks
