Today I tried to mount the RCS 18/20 M/C I got at Dan Kyle's shop. Sorry to say the brake line was about 1/4 inch too short! The OEM and the new M/C at first blush look just about identical. The brake micro switch is identical, the ports are the same but the position of the port for the banjo bolt is slightly farther away on the RCS.
If anyone solved this without having to throw custom Spieglers on it, let me know otherwise it's back to Dan's shop. I made a right nice mess bleeding the lines, BF everywhere..
