2582925 is number on upper tank of radiator. 2582926 is the Chrysler catalog part number. It fits 1966 Valiant and Dart 170 or 225 engine with manual transmission.
Thank you SO much! I am almost 100% positive it will fit for his 61 if he cuts the passenger's side short like the driver's side. I've given him the measurements and he's sure it will fit. Muchas grassy ***.
