This is a set-up from Bob Meyer Race Cars. With a bracket welded to the lower frame rail on each side, the stand is positioned so the quick release ball pin slides thru the frame bracket and into the stand. Welded in the top horizontal piece of 1” sq. tubing of the stand on each side is a short 7/8”OD by 1/2”ID steel bushing that the pin sides into and is secured. Works slick, very stable.
