Headstock tuner bushings
These are the best bushings for my Les Paul jr. They replace the ugly big washer with nut and come closer to the original bushings as possible.

Bushing for Gotoh SD 90 Magnum Locks
The bushing hole in my SG 61 Re-issue were 1 to 2 mm to big meaning that the bushings would fall out when the guitar was flipped over for string change. I just wrapped some plumber's tape several times around each post and finger pressed them in and worked like a gem. I have not noticed any negative effects from this action. The bushings look great and matches the Gotoh tuning posts very nicely and with no slop. I am very please with this product.
