I was in the process of moving to a new house, and decided to have my 1964 Dart Gt inspected and I asked the local mechanic to look at the small leak on my transmission. I needed a car babysitter while I was making my move. He informed me that the leak is coming from my speedometer casing. Now, I paid a good price for this one on ebay, believe $129.00, now 3 years later it is leaking. It has a steel casing. This mechanic is top notch, the old classics line up at his front door, so doubt he is wrong, and he mentioned that it s not an O ring issue. He said maybe I could put a diaper on it. Has anyone else had this problem?
