I tried not to bash RMT in my earlier post, but my experience with them was similar. Going forward I would caution you or whoever takes on your WABCO rebuild to take their time removing the bolts for the little head. I rebuilt my own which is actually an easy job but got impatient and snapped one of the little bolts off. Luckily I work with a very talented group of welders one of whom tig welded a little nut to the broken stud so I could get it out. No harm no foul but cost me an extra day off the road. The bagpiping andy kit is quality and my compressor worked flawlessly after its rebuild. Hope yours does too.
