I purchased a gear-up M20K from Wentworth and then a new 2 blade McCauley prop, model 2A34C216/90DHB-16E. The plane has a very bent 3 blade Hartzell STC, but the 2 blade was less expensive.
Mooney was somewhat helpful with part numbers, but would not provide the drawings of the spinner, and I have not found it to still be in production new. Mooney confirmed that the company who manufactured these spinners is not in business anymore.
Does anyone have a drawing of the spinner and/or aft bulkhead, and/or spacer/backing plate (of which the Mooney Parts Department said two are required.) With this, K&K can probably provide a spinner.
