Scrapbox help needed.

[Morpar]

HELP!!! I need the back roof section off an Athearn F45 from the second radiator fan all the way to the rear, including the radiator grille. I want to add a fourth fan and grille to an FP45 to build a F45X, similar to the SD45X that EMD built, only as a cowl unit. My LHS is out of F and FP45 shells, and says he probably won't get any more. I haven't had any luck online finding just a shell either, so I'm hoping there is part of an F45 shell in someone else's scrapbox. I have some bits and pieces to trade, or would purchase outright. Feel free to e-mail me at [e-mail], just make sure to put something F45 or train related in the subject, or I probably won't open it. Thanks in advance.
