Wanted: SD40-2 dynamic brake hatch

hello from Germany,

perhaps somebody can help me.
I´m looking for a SD40-2 dynamic brake hatch for a projekt.
In the manual I can´t find a part number.
It must be a hatch of the USAT SD40-2. Perhaps the aristo GP40 hatch could be an option.

thank you all
Thomas

they show one for a GP38
part # R22-208

a call to the parts department might be the best bet. They probably have other models in stock as well.
