To the best of my knowledge sleeve hitches were 2 styles, 17-1/2" for the 200 series and 21-1/2" for the 400 series. Lift arm length pin to pin: 200 series is 21-1/4" model # H-22 and K-22. 400 series built before 1979 is 21-1/2" model # H-24 and 400 series built after 1979 is 23-1/4" model # K-24.
