need help !

Can you not find a dipstick tube from a 727 that was in a Dart or Duster?
Typical locking dipstick tube that you bought is probably from a company called Fitz-all. The transmission parts company I used to work for sold them strickly for GM'S. Anyone that phoned looking for a dipstick for a F**D or Mopar were told none available in the aftermarket except Lokar.
