Part Identification
OK, that's two for two! I'll put it in the carb hardware bag.
This is a good time for me to admit that I didn't take any photos of my car prior to disassembly. I've done many auto restorations in my time, including frame-off jobs of some relatively exotic cars. I had always taken lots of pictures during disassembly. When I took the Dart to pieces, I thought it was so simple that there was no need for pictures. I've owned a number of Mopars over the years (including my first car - a worn-out $75 '61 Dart) , so that gave me confidence. Big mistake, particularly because I'm 71 years old, and my memory is definitely not what is was.
Anyway, many thanks to you and the many folks who have responded to my myriad of threads on this forum. I never fail to be impressed at the promptness and generosity of the forum members.
