22 or 26 inch radiator

i have a 70 Demon 6

'70 Demon? My Demon has been made in Sept.1970, but it's a '71 model.

Anyway... when I purchased the car, the original radiator was history, so I looked for an OEM radiator and found a 1971 26 in. (out of an E-body). P/N 3443970.
Got it rebuilt and now it's in the car. So, I can say "a 26 inches rad fits a slant 6/318 22" rad support" and the cooling is just perfect...:)
