Tried tried the 1-1/32" (w/Truck reservoir) and the smaller 15/16" (angled reservoir) - both from Dr. Diff. The bigger one on my Duster requires more leg effort than I really care for. We put the smaller one on my sons BB Dodge truck project (went from power to manual brakes) and it works really well. Will probably go to the smaller unit on the car but like the truck res.

Forget the 1-1/8" (1.125") truck MC's
