Larry,
I measured the door opening:
35 inch wide at the bottom just up from the corner radius
33 inch wide at the top just down from the corner radius
35 1/2 inch wide at the widest point
44 1/2 inch high at aft end just forward of the corner radius
45 1/2 inch high forward just aft of the corner radius
Hope this helps.
