When I bought my 22 Dodge I had no idea what it was. A fellow from Massachusetts told me to look at the firewall. If it had a circle stamped in it with 4 fingers pointing at 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock. Then it was an early Dodge. Hope that solves the mystery. Good luck.
This one has just been discovered. ( in the USA ofcourse ) The story is over at www.prewarcar.com . It still has it's original winter hardtop conversion.
