Now that I am putting the stratton 3 point hitch on my '56 CJ5, Seth aka @windyhill said I am the stratton three point hitch guy. I want to start a thread documenting these hitches. On the control valve, there is a data plate with a number which is the serial number I am assuming. The stratton lift I have came on a '63 CJ5. I'll post the numbers up of this jeep tomorrow once I get my hitch serial number. Here are some scans of an original stratton hitch brochure.
