Coming out of my '71 LeSabre with about 61K actual, in favor of an overdrive. Original to the car. Little old lady car until I got it at 51K. Works fine. Originally behind a 350-4. I don't have the numbers off of it yet, but the car was a relatively early production example, guessing Nov '70. $150.- plus shipping. Jim W. is doing the switch, so it will be at his shop in Pine City, MN.
