Check on your trip mechanism and see if you have the part number HTP 8. Also on the colter arms you should see the number HTP 237. On the furrow wheel arm you should see the number HTP 17A. That is what I have on my plows and I have been told they were AC plows but I don't know for sure either. If I knew how to post pictures on here I would send them.
