Electrical need help with a part number

hello, one of my HVAC controls stopped working recently, the vent control. I took it out and the piece circled crumpled into bits in my hand so I bought a new one off eBay, part number yh-1447. it works well except the knob does not match the controls, everything is rotated 90 degrees counter clockwise.

The weird part is the knob fits everything functions fine. does anyone know the correct part number for an 89 GT 5.0? Thanks!
