Its hard to say without seeing. I know a deck from 1445 won't fit. The 935 has the gear box offset to the left and the 1445 was centered. Also the angles on the arms was different. I don't know if an 1145 uses the old 935 style or the newer style.
Please post up when you find out. I'd like to know as well. I need a new deck for my 932.
