You could have mentioned it was the 69 503 light green.

Use the drop downs for chevrolet truck and then 1969. It will provide the codes. Then go over to the left and pick out what you want for a system or just call tech support. Tell them you want the 503 PPG Ditzler 43523 and need a recommendation for a BC/CC system it will probably be the UB and RC series. Get a system price from them for everything it might work to your advantage.
