Is there any value to these old parts other than scrap value ???
Try AACA(antique automobile club of America) . But you are going to have to catalog this stuff. You do seem to have a mix of years & makes. I personally think I see a 3 speed that would fit my 37 ram, not that I need one. But then shipping is going to be an issue, a lot of that would be better local pickup only. My opinion is I would want as much as possible to go to people that need it, even for free. But I hate for good iron to go to scrap.
