I went to the parts store and picked up a rad for a 74 dodge 1 ton dually. It dropped right into my 71 demon. Used a shroud that I got from the local chrysler dealer from the restoration parts book. Regular old clutch fan and the car never goes above 180. Dosn`t matter what the day or temp is outside. Been this way for 4 years now. Most parts stores that sell rads with have pics and dimensions or the rads in the back of the application book. Do the measurements that you require and pick a good 3 core that fits your requirements. Easy-Peasy.
