SD45 Spectrum shell

[Jerrys HO]

I have two of these loco's, one is Union Pacific item#82708 and the other is a Great Northern item#82714. I have searched the internet and the Bachmann part's page for a replacement UP shell with no luck.
Does anyone know or have one that they would like to swap for the GN or sell? I put a call into the parts dept. and did not get an answer yet, will try again today.
I know I have the option to paint it,but prefer not to as these are very detailed and beautiful shells and would hate to screw one up as the cab comes apart in 50 million pieces and would hate to destroy it trying to remove the glass,engineers and led mounts.

Thanks Jerry
