Mitchell Overdrive - Shift Lever Knob - Ruckstell?

[DougVieyra]

I have a Mitchell Overdrive with shift lever. For a visual connecting link to the past, I thought I might remove my existing knob on the shift lever, and replace it with the knob made for the Ruckstell shift lever. With Ruckstell being a highly recognized over-drive unit for the Model T, and with it's shift lever knob highlighted with the highly visible word "RUCKSTELL" across the top of the knob, I thought it might look more historically correct.

Snyder's sells the RUCKSTELL shift knob ($5) but I am wondering if the threaded female hole of the knob would screw right onto the Mitchell shift lever.
Has anyone who has a Mitchell O.D. tried this - or does anyone know if the RUCKSTELL knob would fit the Mitchell shift lever?

I know that if it does not, I can do all sorts of things to MAKE it work, but I was hoping to avoid any unnecessary hassle, by having it just screw on without any additional hassle.
