Rear Disc conversion super noisy?

I just put the same Right Stuff rear kit on my cuda last night and it was easy. Everything fit fine with the exception of the e-brake cables. The kit gives you 2 that are the same size, one is about 6 inches too long for the drivers side, and the other one is about 4 feet short for the passenger side. I will call them this week and see about some different cables and see what they say. So far, it looks like a quality kit. I picked mine up from the Indy Cyl Head show form Right Stuff at their booth. Really nice guys to deal with. My cuda won't be running for quite a while yet so I can't tell you how they work yet.
Question for you, what master cyl are you using? and did you remove the green bearing retainer plate like the instructions said to? I left mine on because it looked like the bearing would slide out if I did. I have some pics of the install that I will try to post sometime soon.
