Installed the JBR Chrome-molly RMM 2 days ago and seems to be working great (hopefully the vibes go down a little), Customer service was top notch and overall i love it. One thing to point out tho.... When it came in the mail it had a bolt with 2 washers, a nut and a lock washer. The directions didn't specify what to do with the 2 washers. I used the OEM bolt, lock washer, and nut. Is this correct? Are the two flat washers needed? The OEM bolt doesn't seem long enough to fit any more hardware.
