I'll have mine off in a few days and will take pics. As far as I know, NOBODY is making a two bulb unit at this time. I looked into this extensively and none of the suppliers carried them. It seems to me they are all carrying the same unit and selling for the same price etc.

The two bulb, original unit on my Bird worked from the day I bought the car to the day she was parted out. It worked perfectly with points, HEI and Pertronix all WITHOUT any additional parts etc. It lit up perfectly and it NEVER had ANY condensation problems. Looking back, that's the one part I wish I'd kept!
