God, it sucks to get old...ha. The old friend w/the Valiant convertible 273/235 car calls me back awhile ago tonite to confirm that he ORDERED the car in late '65 and it actually was a 1966 model....hopefully, I didn't confuse anyone in-the-know w/all this....and the car had a 3.91 rear gear--not a 3.90. Best wishes.
