Apparently I used too much force trying to take the nut off the starter and it sheared the bolt off. Does anyone know if I can just use another mount point on the starter or is that one special for any reason? I could try welding another stem to that mount point if necessary but was hoping to avoid it if I could. Any thoughts?

Sheared Ground bolt off starter while installing ground harness

Yeah, I had that part right. 
It was about halfway off before it snapped off. This thing came from S. Ga near the coast and has more corrosion than I would like which assisted in the stuck bolt. I thought I could muscle it off and didn't think it was near enough force to shear. From the looks of it I think I can use a mount bolt to ground it but I haven't found any info to confirm that yet.

When they start to get tight go back the other way and put some penetrating oil on it and keep working it back and forth, don't force them.Yeah, I had that part right.

Doesn't really help with the problem at hand, I'd try it with a different ground point and if that doesn't work, I guess its time to take it to a starter shop.

Your right about not helping the problem at hand , but it might keep someone from having the same problem in the future.

I agree! I've found that heat helps too.

Sounds like some presidential engineering to me. I'd pull it and take it to a shop to replace said bolt. Maybe clean up the armature and throw some new brushes in too.
I agree I should have backed it off and used lube in this case. I was partly in a hurry and it was almost off without too much trouble and snapped without what I thought was a large amount of force so I suspect it was already weak. You can see the corrosion on the stud in the pic so it was probably already weakened. I definitely will be more careful in the future.

As rusted up as that is I would pull the starter and replace the stud , if your not comfortable doing it yourself take it to a shop.
The labor to fix the stud if fixable and then to freshin up the starter would probably be more than a surplus new starter.
As rusty as it looks....the rest of it may be pretty corroded.
Starter has another mounting stud which goes in a bracket at the motor mount......they get loose in bracket, and then one or both main
mount bolts break off......fix it all when starter is removed.
There are two types of starter / motor mount brackets....the weak early one, and the late beefed up one.
I have a new starter and late style brackets available if needed.

Any chance of posting pics showing the difference?
