T-3 Headlights - Whats correct ???

[Tommy]

68 copo, I pulled A T-3 off an unmolested 68 chevy II this year and it has the vertical lines inside the T-3. I am not sure where the dates are on these but if you can tell me i'll let you know what they are if that will help you. The car I pulled it from still had the original dated plug wires and A coil I had never seen before, the coil wire slipped in and screwed down ? The car was complete and looked like it was parked 25 or 30 years ago. Original belt,alternator and even the complete original exhaust system. I think the light may be the original too. Tommy
