Thanks MTCK! I checked out the enclosure you mentioned. Looks like a great unit, but unfortunately I don't have enough room behind the seat with the power window unit back there:
That photo is with the bench as far back as it goes.
*I forgot to post yesterday - When I was converting to the HD brakes I had a heck of a time finding the correct components. The parts guy had no idea which listed parts were assigned to the LD or HD brakes, so here's some part #'s. Most part stores can cross reference them with other manufacturers.
Rotors - no part # but make sure you get the 4.95" overall height or the 1.25" thickness
Calipers - A1 Cardone 18-4126 and 18-4127
Inner wheel bearing - SKF BR5
The other components (outer wheel bearing, dust seal, and hoses) are the same as the LD brakes.
