I have one from my 63' Dart. Was a Slant 6 with a push button. I think they are the same, auto or manual. It is approx. 59'' long from the end of the gear. I have a extra 19 tooth to go with the 17 thats on it. Turns free but will need cleaning and lube.
Henry the parts dog is in a good mood being EARTH DAY and all.
He says you can have it for just the shipping! I live in Colorado, 81301.
Should be around $20 $25 US to ship to France. If you use Pay Pal I can send an invoice. Send me a P.M.
