USED WOODGRAIN 4 SPEED BALL KNOB

Orig 4 spd.knobs no matter the wear are not getting thrown in the trash. They are worth a chunk of $$. You saw the price of the NOS one? It's not unheard of.
Get a repop and scuff it up. OR get a chunk of wood and make one. I cant see making one being that difficult.
Old used ones are worth a good penny.
Good luck.
