On my trim tag there's the normal rows of numbers but on the top right corner near the screw there's a large stamp that appears to be a .4 overlapping the uppercase Z. any help is appreciated, Thank you!
I have a 1966 Plymouth Fury 2 c body. She's my first car. I don't know too much about it as I'm only 17 years old and I need all the help I can get.
