440 ICD Transmission

[cuznguido]

I know this is going to be a long shot, but does anyone know of a good transmission (5 speed) for my 440 ICD? Mine is all there but is going to need a complete rebuild and I would like to avoid having it torn down for what might turn into months while I chase parts. I would be willing to drive a good ways to get one ready to use, if I should be so lucky. All assistance is much appreciated.
