PSI adapter plates were designed to be used without altering the instrument panel. This requires the head and plate to be held in place by a single clamp. The supplied clamp can often be modified to be adequate, depending on the size of the parts.
With a PSI-118, bend U-clamp legs outward enough to hold head and adapter plate in panel. With PSI-128, use clamp from old head or bend clamp as shown.
