I ended up buying the EBC double sintered. I originally posted about my difficulty in finding a EBC part number for the rear.
I found part numbers for the front, but not the rear. I came across an Amazon part number that was for the rear, but labeled Front in the ad.
I had my local dealer order the correct EBC number for the rear and it is EBC FA630HH
I have installed with no problem. Since it's 40deg today, I'm not able to test ride until warmer weather returns.
Thanks for you suggestions....... Larry
