Itty Bitty Bulb needed

I posted an insert from the FSM documenting the part# that was posted. I can confirm the part # in "larger font" if you need from several GM SPO publications. I mentioned "if you have bulb in hand to compare dimensions to the T3 and T4" - I wasn't "on track" - you're the guy with the bulb/socket in hand.

It ain't a #74

here's an entry from SPO - switches and LAMP/BULB in same parts group!
