Hi There Larry;
I have one in My "Glove Box" (Not For Sale): The Dia. of the Knob is so Small; Its a really Strange Feeling driving with It on: To Me, It almost feels as though your going thru the Gears just with the Gearshift Lever & No Knob:
I drive with a Wooden TR Knob & When @ Shows, Just put the Orig. on "For Show, Not for Go"!
What did the TRF Charge Yourself?
Regards, Russ
