i used 3/4" heater hose for the PCV and a plastic moroso catch can. (the breather has rusted so i wrapped it in cloth tape.) the unit fits well nestled adjacent to the rad fan shroud. i drilled one small hole in the lowest edge of body metal there - sorry, don't know its name - to accept the drainage hose barb. since it sticks out a little bit, i may cut half an inch off of it to make it less proud. between sitting in that hole and the hose pushing it into that corner, it seems secure enough. the valve for draining it is just inside that bodywork.

my internal baffle still needs work though. there's not very much stainless steel wool in between the gas inlet and the breather, so i still get a little bit of oil blown out of the breather. i think i may need to angle the gas down into the scouring pads so that it has a longer path before reaching the breather.
