Wanted: 440 crawler parts or donor machine

[Kent]

I have a JD 440 ICD and need right side (as you are seated) final drive parts: Bull and pinion gears, bearings, cast oil pan (under Bull gear), final drive shaft, etc.
If you have any of these parts or know where I can get them or know of a unit somewhere I could use as a donor - please let me know.
Also, if you know parts interchange information that would be very helpful for me to expand my search.
Thanks,
Kent
