I have a late 1989 or early 1990 Ford 3910 and am searching for replacement lower lift arms. The aftermarket is loaded with every lift arm imaginable for these old school tractors but Ford seems to have pulled a fast one on us or as I call it, they "John Deered" us. The arms on the tractor right now are OEM part number 82002004. Every aftermarket option references this number. The problem is the OEM CAT 2 ball on the tractor end 1 1/8" wide and all the aftermarkets ball ends are 1 3/4" wide. I contacted Yesterdays Tractors and spoke with a gentleman that was able to have their aftermarket arm option measured and they measured 1 3/8" wide so I am ordering a set of those. I can make those work I do believe. Has anyone else run into this? If so, what was your solution? I will post back with the results so maybe anyone in the future dealing with this will have some help.
