I put an OER from Classic Industries in my 70' Charger last summer. Looks just like the OEM factory radiator but it just doesn't have the tank numbers stamped on top. Everything bolted right up as needed & hose location were in the correct positions as well. My car also will now idle all day in Woodward traffic and not overheat. I am happy with it so far.
I had a complete custom radiator made for my 70' Challenger to support the 1000 HP on the street. It has a custom made shroud & dual electric fans incorporated in it. I had them try to keep the Mopar look & had them add the -20 weld bungs for the AN fittings for the upper & lower hosed to keep with my "race car but looking kind of stock theme".
