As the title states, I am in the process of getting the parts to do the conversion, and the only part I have left to source is the calipers and master. I have the forks from a 2003 636 plus axles and spacers as required. I also picked up the 10mm spacers for the calipers. I know the matching year calipers from the 636 fit, but all the units on ebay right now are crap. What other model calipers will work with stock front rotors on the 636 forks?
