Vintage air gives the dimensions of their units in the catalog. You could build a trial unit out of cardboard and tape to see what will fit. If you don't want to got to that trouble, they also sell dummy units for trial fit.

You could also give them a call. They have sold thousands of AC units and no telling how many of those were for 32's. They will have a good idea what will work.

PS - Jack types faster than I do!
