I know this may sound strange... but years back I printed and laminated the attached (4x4 photo from Corey). I keep it in my car. When I drop it off at the shop, or valet park at one of the local hotels/ restaurants (typically car is left up front but they always want the keys just in case they have to move it) — I hang it from the whipper button... to avoid the “ I could not move your car because I could not get it into reverse” comment. And most importantly avoid a damaged knob. Yeap...one of the wood woodcraft was cracked in a mechanics efforts to find reverse. ( my knobs don’t have the gear pattern on them).
I was using the tradition M10 356 knob until I installed one of the woodcraft knobs,
