Sleeve Hitch brackets for most Case and Ingersoll tractors. That means all 200 series, 400 series, 3000 series, and 4000 series. Now, some of the very late models, such as the 4200 series, use brackets like these, but the flat of the mounting bracket is too thick. This bracket could still be used after some grinding on the bracket.
I made this a complete kit. The bolts and lock washers are included. The clip is also included. It is supposed to be used to keep the sleeve hitch mounting brackets with the sleeve hitch when the sleeve hitch is removed from the tractor.
The part numbers are below. They are NLA at this time.

Each bracket was over $80 when they were still available new, and they did not include the bolts, washers, and clips.
