John, I had sent Bill my address but if I choose not to use them I will send them on to you. Scott's idea of reworking the parklight sockets sounds interesting. The rear already has double contact for park and brake lights.If I hooked a signal to each side of rear could the current travel back around to the other side thru the brake wire?
Also now I am very curious about Spanky's suggestion of GM Guide D68's.
This old truck came without signals or heater.
We will have to find a heater before cold weather. I told my son to use arm signals when turning and he wanted to know what that was? HA!
