Which Other Manufacturer's FT Shells Fit The Stewart FT Chassis?

Looking over the Posts on various Manufacturers F-series body Shells that will fit their different chassis, my inquiry is :

What Manufacturer’s EMD FT shell (A or B) will fit onto the Stewart Hobbies EMD FT Chassis?

ie: Will a Bachmann FT body Shell fit onto a A Stewart FT Chassis etc?

Appreciate advice.
