Installation Method #1 — Preferred
When installing, remember that the car is supported near the center of gravity. The center of
gravity may be offset towards the front of the car to compensate for door operator weight unless
the car has both front and rear doors. Install the target bracket as close to the center of the floor
as possible.

To measure the compression of the rubber pads and not the sagging of the floor – attach a
structural piece such as a 1 ½" by 1 ½" angle to the outside edges of the floor.
