Hi all. I have a 1961 Canadian GMC half ton. I am wanting to replace the lenses (clear) on the front parking lights. However, they seem to be different than later years, in that the lenses appear to be held in place by 2 rivets? How does one go about replacing the lenses with this setup? Also, I got replacement lenses from Classic Industries, but they look like they are held on with 4 screws. Anyone know if these can be made to fit? As a secondary question, why the dual filament bulb? One for park light, and one for turn signal, I'm guessing?
