[C320-list] Adler Barbour Compressor Base replacement?

[MARTIN and SUSAN RAPHAEL]

The base to my refrigerator compressor is very corroded -- does anyone know if this is a part that can be replaced, and if so, how to obtain the part and how to replace it?  The compressor sits in the port locker and gets exposed to moisture...I've tried cleaning it up, but the corrosion is just getting worse and I suspect performance will suffer before too much longer.
Thanks,
