this is incredibly easy to do I followed Troy's instructions the front leg was 20 inch long as took off about 35 to 40 % about 7.5 inches of the 20.
I think the same could apply to the 22 incher. If it is 24 inches long(IDK how long it is) take off 9 inches, you would take off the same on the top of the two back bars as well.
With the triangle cut the outside triangle and make it fit.
@pbe gummi bear what do you think a mini 22?
