Mower deck housing replacement

[WilliamTO-35]

I own a Deutz Allis 914 hydro , made by Simplicity in the early to mid 1980s . The corresponding Simplicity model would have been the 7114 H.
The deck on my 42 inch mower is rusted out beyond further repair , and I want to buy a new housing. ( Just the stamped sheet metal piece.) The Allis Chalmers 914H would have been an equivalent tractor. There are new replacement decks available online , but determining exactly which one to buy has been confusing. Can anyone help me on this issue ? Thanks .
