I'm a new guy and probably will have a lot of dumb questions. I purchased a 1977 FJ40 and need to replace the bulbs in my instrument panel and Dash Pad light. I went to Super Bright LEDs and see that there are two choices for the instrument panel lighting (Stock #158 and Stock #74). Can anyone tell me which bulb or combination of bulbs I need? I'm not the most mechanical person so I have not removed the instrument panel to see what bulbs I may need (don't know how). Thanks!
