The 36 gas filler neck comes out of the fender on a different angle than 35. You can't just swap left side rear taillight brackets to make this work. You can't change to '35 gas filler neck unless you add a vent tube like the '36 filler neck has. Probably a dumb question, but why wouldn't you keep the left side '36 taillight assembly like it is, and find a right side '36 taillight assembly the same length as left side and use that? I always thought '36 taillights look good on a '36. Of course it's your car and you can do anything you want to do with it, as long as you can make it work.
