I found - and brought back to life - a hold down clamp that was in my stash. My car had been devoid of one since buying it. In a conversation with Dave Johnson today, he sent me a picture from the assembly manual that depicts a different clamp used on Flint cars only. My OCD is kicking in but I have to draw the line somewhere. Is anyone with an original Flint car able to tell me if there's is painted or clear metal?
