28591 Western Ultramount Blade Quadrant Midweight Plow 7/8 Pivot Bolt

A New Factory (part #28591) Western Quadrant for the back of the Midweight blade. This is the same for Steel and Poly. This is where the A-frame bolts and the springs hook to.

This uses a 7/8" bolt in the quadrant to the Aframe. 

The later Midweights used a 1" bolt, that is part #49531. 

Any easy way to make sure you have this version - the pivot bolt is 7/8". The newer version 49531 uses a 1" pivot bolt (otherwise they look identical).
