FJ40Mitchell has the bulbs spot on. I just replaced mine with those bulbs and they are the perfect upgrade for my 73 FJ40. Word of warning though, I spend many-a-hour cleaning every part of the dash cluster including the odometer. None of it had been touched in years(Lots-o-years). The odometer now works perfect and the lights are perfect for night time driving, and I am very picky about my dash lights at night.
Good luck to all.
