All you need are:<br>
<br>
15 mm x 1 threads per millimeter tap.<br>
14 mm drill for initial boring prior to tapping.<br>
A 15 mm x 1 threads per millimeter bolt at the length you need.<br>
<br>
No special tooling, no excessive drilling diameters, etc. A single thread per mm is a course pitch so it meets that requirement. This is all fairly cheap, straightforward, available from major Internet retailers and probably your local fastener store if you have such a beast. I am lucky - I have three.<br>

<br>
Anyway you go, best of luck.<br>

> My white demonstrator Super A that I have been tinkering off and on forever had four badly stripped holes in the torque tube. Somebody had tapped the 5/8" holes out about 7/8 or so and it was BAD. There wasn't any threaded inserts that I could find that would be direct replacements. A machine shop friend of mine was nice enough to make a set of inserts, kind of like the KeenSerts, and install in the torque tube. Once it's painted I don't think you'll be able to tell that anything ever happened to it!<br>
