The shafts get butchered on purpose sometimes. On the directions for installing the yokes on some installations the instructions called for cutting the shafts shorter.

I went to the Forney style (no longer available new although maybe from one of the dismantlers). About half the time people change control wheels, the shafts get butchered. I examined one control wheel shaft example with a outside diameter of 7/8", an inside diameter of 5/8" and an approximate length of 17-1/2". Try calling Univair for dimensions of part no. 415-52055-2 (the drawing number is the same as the part number) for an authoritative answer to your question. The Forney control wheel shaft was part no. F-52078 which I show varied in production from a length of 19" to 19.431 and apparently later to 19-11/16". If your shaft universals need replacement, the MS20271-B10 may be an "or equal". Aircraft Spruce has these at $83.25 ea.. Hope this helps, William R.
