Important Buying Note:

Mounting hole dimensions are always referred to as "Oldschool" or "Newschool" patterns. Both share the same horizontal width (parallel to the hangar), but the lengths (running from nose to tail) differ.

The width for both is 1.625"/42mm. The Newschool length is 2.125"/53mm and Oldschool length is 2.5"/64mm.

Always check to make sure your deck and trucks have compatible mounting hole patterns, or brush the dust off your drill press........
