Yep, Midwest is sort of a one-man operation. He sold me a NEW Hydro for about the same price. (didn't even know you could get new ones, but the one he sent definately was.)
He does the rebuilding for the guys in Pittsburg, then in turn everyone gets them from Cardone. But we cannot buy from them unless you have a parts buisness.
It was for my 57 GMC 370. Got great brakes now, after new lines, all wheel cyls. and a MC rebuild. Used the same shoes, since they had about 1/2" left on them. Just figure $1000 to have brakes on these Big Bolts.
