The bushings for the Economy tailpiece are large. The holes in the body would have to be made bigger. Bushings are .475 and the holes are around .433 . While not impossible to do with a hand drill I would definitely rather use a drill press for this operation. The tailpiece does seem to line up well enough.
The Gotoh bridge lines up perfect. At .438 the bushings fit much closer though still too tight to just pres them in. I would need to expand the hole one drill size to make them fit easy enough.
The slanted Bone Nut from ALLPARTS needs a little trim to fit the slot. I think the LP nut would fit perfect. This is a generic martin style I had lying around. In the picture you will see it is larger than the 1/4" file from Stew Mac. Probably just cut my own from stock.
Black Metal Curved pickup rings from ALLPARTS. The fit is not ideal. If I was going to use them I would have to put a piece of sandpaper on the top and sand them to match.
