Stick,

Just saw where you have a JD 420C. The 420's were made from 1956 to 1958. You can check what year it is for sure if you still have your serial number tag. I have a JD 435.


Beewrangler,

If you still are having trouble finding the original GM numbers, let me know and I can check in my parts book.
