1936 Pontiacs must have all been used-up? I have been looking for tail lights for 8/9 years now & other than a few lenses & frames ( that I have grabbed ) I have not seen not one housing or the stands they mount to. I have not seen any body parts or project cars showing up anywhere for sale? Where did they all go? I want a pair of these taillights & stands....
They look a lot like my 36 Chevy tail light mounts. I have a search in E-bay for anyone that lists tail lights for that vehicle. Not a lot of hits but every so often one shows up and if its decent I'll grab it. I suspect GM used similar if not the same tail light assemblies with different lens for there various models. Look at any GM car in that year range (35-36) for potential matches.
They look like the ones on my 1935 Buick. I would need a close-up picture to be sure. If they are the same you could get the Buick ones from suppliers of Buick parts.
You could contact the Buick club of America......(763) 420-7829...........ask them for help on what members sell parts, etc.
