Spare spark plug holder for the cutdown.

A couple of years ago I got two aluminum spare spark plug holders from Tom in Japan. They where both pretty fresh from the foundry.
One was fitted to my Panhead girl Bessie, the other have been on the shelf since then.
I just whilst working with the cut down project, came to think that it would be a cool accessory on that bike too.
Had to drill and thread for 18mm spark plugs, no problem as long as one is careful.
