Hello, This m/c came with an "under the floor" power brake kit,it said Corvette style,I thought it was refering to the ports on both sides. I did order the unit for discs front, drums rear. I checked it for the builtin residual valves, (saw on an older form somewhere on here),by inserting a toothpick and if it stops about a 1/4" in ,it has them, but it didn't.....so I'm assuming it doesn't.
Thanks,Brian
