It is TIGHT with the FMS alum. DS. I had to install the bolts from inside the loop and put the nuts on the outside to clear, and even then it was close. Don't make one unless you have access to some thick ass metal. I had a U joint fail and the DS loop saved my ass, but I TORE IT UP. I mean I bent the crap ut of it, I had to take a sledge hammer to it to get it back into shape. I hear the HPM has more clearance. If you go with the FMS/Lakewood one, MAKE SURE you triple check the alignment of the DS to the loop to make sure that there will be no interference.
