GP38 frame issue

So I had a problem with a GP38 that was having issues running, so I took it apart to clean it.
Big Mistake.
As soon as I pulled the screws out, the frame fell to pieces.
I am a little torn up about this, as this was the Santa Fe unit I modified the pilot to have a plow and body mounted coupler.
Any idea where I can source a new frame?

Or at least if need be email me at my username here @yahoo / @gmail if you would like to.

Thanks!
