The recommended mounting of the breather is for the "in" port to allow a straight drain back to the differential; obviously the whole assembly needs to be above the differential at all times. Since trunk space is at a premium in the OneLapCamaro, I fabricated a bracket on the back of the rear bulkhead "Y" supports (behind the upholstry) which puts the breather well out of the way:
I have two large rubber grommets for the remote reservoirs which I am using to pass the line from the differential through up into the trunk. On the input side it will be a straight shot into the breather, on the "out" side which will terminate with the K&N filter I ran a line across the trunk, and out on the other side:
Unfortunately, I ran a touch short of -6 hose and will have to wait until Monday to finish this up...
