i have a 67 and the right side tail light is driving crazy ,works when i leave the drive then down the road it quits ,i`ve replaced the pig tail already, it fits a little tighter than the old one but still have the same problem any ideas? graemlins/sad.gif

Had the same problem with my back up lights, 99.999% of the time it's a ground problem. try wire brushing the socket where it contacts the housing. That's where my problem seemed to be.
