I don't think there was. I know exactly what you are talking about, I got one of the Rippers from the first build. A friend of mine got one six months later and his was machined for more clearance there.
The next time I pulled my trans out, the rubber boot had hardened and cracked all apart, so I called B&MM to see if I could get a replacement Ripper and explained the whole rubbing thing with the grooves that had worn in the housing. I was told they couldn't replace the whole thing, but they did send my a new boot free of charge.
I took a dremel and made more room where the grooves were wearing. Then took it all apart to clean out aluminum chips, regreased and reassembled.
