Here are the CORRECT parts to make this conversion.......

Aircraft Spruce.........need 2... 06-01311 Rapco Brake Disc RA164-09900
Aircraft Spruce........ need 1... 06-00651 Rapco RA66-106-4K brake line kit
Aircraft Spruce.........need 4... AN4H-16A AN Bolt
Granger...................need 2... Arbor shim,0.1250x1 1/4 ID. Granger sells a pack of 10 only 5GB11..... so shop around.

Why do you need an 1/8" arbor shim?? When you install your home made 1/8" spacer between the pad plate, it moves the entire brake cylinder 1/8" closer to the pant bracket. Test fit for scraping. If it does not scrape, you may not need the shim. The 1/8" arbor shim will move it back to it's original location. So if it didn't scrape before, it won't scrape after. But now you have pushed everything 1/8" out the axle. So you must remove 1/8" from the face of the nut to bring it back to it's original location.

ACE hardware..... (or any hardware store) Alum-flat 1/8" X 1" to make spacers to move pad plate out.

Local Hydraulics shop....need 2... Viton "O" rings for piston. Viton # 568-218. https://mykin.com/orings/as568-218-viton-75.html

Machine .125 from the face of the nut to make up for the shim and allow the cotter pin to line up with existing hole in the axle.
