David,
The basic measurements are 3 5/8" thick at the top tank, 25 7/8" wide and 29' tall from the top of the upper tank to the base of the bottom tank. There was an add on MLU, this summer that was for a WW 11 generator. It was powered by a period Ford flat head and the radiator certainly appeared to be the same. I'm suggesting that this radiator was used for more than the Lynx.
