Unity does not carry the short handle, it will have to come from an original spotlight sold by GM. It appears all GM spotlights had the same short handle whether for a Chevy truck or a Buick. There was also a short Ivory handle that supposedly came with GMC spotlights.
Be sure to check for the correct overall length. The Unity "A" length I have mounted in a 141L bracket is 14 1/4" overall from the forward end of the headpost housing to the back of the switch cap. Unity measures differently, (center to center) from the center of headpost to center of handle. The "A" length center to center is 12". Some early spec sheets list the "K" length instead, which is 1/2" longer at 12 1/2" c-c.
