Above are all of the Pat # i can find in the unit. The locking cylinder that holds the swivaling arm and crank broke (you can see in the picture). It seemed similar enough to this post, my unit has four screws that holds it in place.
Please help!

Thank you! These should be it, the only difference is the length of the arm it seems. I'll measure it and take it from there.
One last question. Are all of the crank handles I choose to go with the same fitting? I want to go with a shorter handle, but want to make sure it will fit. I don't see diameter specifications of the crank handle's slot
