I would not be surprised if this distributor is from the original engine in the car. The carburetor I replaced shortly after I moved to wyoming. I remember I was going over the bighorn mtn back about1995 and the carb went kaput. I made it to Gillette and bought this one off a larger six. Drove all the way to Pittsburgh and then Oklahoma. Has more power given bigger throat, but not sure if a good match for that old distributor. The engine was definately firming but not sustaining. Maybe I should try a new set of points, or even get electronic ignition, what do you think? This carb, It has a larger throat and is marked C5TFG. On the base. Above the base is a small circle with the number 1.29. Here is a picture of what is on car. Notice manual choke. Also two older carbs that have been sitting in a bucket
