Sorry to be late - -

The stud is often made of AL. I replace the stud with a steel 1/4 X 20 and then solder to the top. This make for a more original look and the original connector/connection at the base can be reused.

That's ok bud...I don't seem to see notice of replies either until late, or I'm not checking the right email or something.
Hindsight shows I should have cut at the bottom, maybe a 1/2" up, as you and John Bartley suggested. Someone else suggested cutting along the groove at the top.

If I can find a suitable replacement for the one I butchered , I may try this. But I'm not too hopeful.  I will probably just put them underneath.  Thanks.
