Answer
I can't answer your question, but I suggest you go to the walter p chrysler car club site.  I'm sure the answer is there someplace.

Join the club if you have too, or find and join a club near you.  
Good luck, and get back to me if you continue to have trouble.  I am a model A guy, but I can help you find your info.
