I'm about to give up driving at night!

I changed most bulbs in my 69 Dart at different times. 71 may be harder. I was young and skinny then and it wasn't easy, allowing just 2 fingers on some. Probably easier to pop the dash out. While there, check for speedometer wobble (may need a shaft bushing), loose pins on the circular connector, Vreg, etc. I put LED bulbs in my cars since they are supposed to last much longer. Search on ebay for the bulb#.
