John Deere crawler top link question

[jay563]

I recently saw at someone's place what might be a John Deere crawler top link bottom part but am not sure. Comparing the piece the to the picture in the parts catolog, it looks pretty close. Someone screwed a part of another top link into in tho. It was green in color and had the piece semi circle to hold the adjustind rod. The only thing that i could not figure out was that this piece had a different part number than M3560T which is listed as the toplink for John Deere 420 or 430. The part number on this did not have a letter as a start, but had 5 to 7 numbers and i forgot to mark them down and it ended in the letter A.

Could this be the bottom piece of the crawler toplink with a different number then, that is what i am not sure about or is this off another tractor? I asked someone who knew them and said that the place did own a John Deere 420 crawler years back too.

Thanks for any help
