 I used three inch blast gates designed for sawdust removal in wood-working shops. I used the aluminum versions because they are stronger and are held together with screws that could be used to attach mounting brackets. |
 Cable mounting brackets were attached to the gates to hold the sheath and wire of the push-pull controls. The controls should have more than a three-inch operating range. Mine were too short and would not open the gates completely. I will change to longer controls when I find them. |
 | The resulting assembly is self-contained and does not require any additional mounting holes or brackets. Three inch holes are drilled in the floor boards and two mounting bolts hold the blast gate to the floor. Two of the four bolts around the blast gate center circle were used to mount the assemblies to the floor. Space is limited for the driver side three-inch hole in the floor board. The easy mounting is between the accelerator and brake pedal as shown in the picture. |
 |
 The drivers' push-pull control was mounted just below the emergency brake control. This location was chosen because the mounting was easy, the driver could reach the control, and no holes were required in the dash. The control is not heavily used and so it was mounted out of the way. |
 | The passenger side vent was mounted as close to the side of the coach and as high as possible. I did not want to make a hole in that excellent, flat floor board that the passenger uses all of the time. The push-pull control was on the floor below the vent hole for the same reasons given for the driver side controls. |
 |
 The input hoses to the blast gates were also sawdust removal equipment. The locations chosen for the blast gates allowed the hoses to be easily routed to the front of the grill. The current hose mounting is in the grill. They are squashed slightly and pushed out through the center slot of the grill. |
