Bachmann Diesel Locomotives - Swapping Shells

[DavefromMD]

Are the Bachmann DCC equipped diesel locomotive shells interchangeable with the Bachmann DCC equipped with sound diesel locomotives?
I have GP38-2 DCC equipped and GP 38-2 DCC equipped with sound and would like to swap shells.

As far as I know they should be, however bear in mind, that getting everything to fit after swapping can be difficult as the sound models are often a tight squeeze.
