In my quest to be a little bit different I took the PMB rack and welded some 3/8" round stock tabs to the pannier protecters to match the birt bagz mount. The strap goes down to the loop on the rear peg mounts. The bagz worked great.
The sheepskin is from Alaska Leather, Barb will hook you up, the best 40 bucks I've spent in a long time. It goes on and off in about 30 sec. If I remember right it is a "pillion 1".
