My D2/3J takes the same nut. I believe the 5J takes the same also. You should be able to find one on this site. I bet alot of other model cats used the same nut also. It's a longshot, but you could try Cat. Still might have one left on a shelf somewhere. Go to the vendor list on this site. Lots of people to call there for the part your looking for. Hope this helps😊
I checked is my high SN D4 6U book and it is the same as your part number and by memory most the tractors in that era used the same adapter nut as yours so I,m sure Cat would stock them yet.
Thanks guys for the replies. I'll give Cat a try on Thursday.

Hey Perry with all the parts Cats on this list I'm sure there is a few of these floating around. I probably have one laying around that I'll send you if no one closer steps up...
