Would appreciate any information, photos or experience with fitting an aftermarket radiator in a 70 e-body w/ 26" radiator opening. I'm looking at the Be Cool #80178 or 60178 (or other brands anyone has experience with), they claim 2 holes drilled in the top of the sub frame for mounting, no issues with that. There's no mention of mounting for the top of the radiator but photos show a tab that appears to bolt to the upper radiator support? Relocation of the battery, can the tray be moved back towards the shock tower, trim the front of the tray & use a smaller battery or ? How extensive is the battery relocation with some of these radiators? I don't mind the small easily repairable modifications, it's what they don't tell you I'm worried about.
Thanks

Check out Griffin they make a bolt in aluminum 26" I just installed one in my 70 Challenger with a 528 hemi. It dropped right in no mods.

I used a Mancini "muscle car" top tank aluminum radiator. It fit stock mounting and used stock replacement hoses. With the matching shroud and MP thermal clutch fan it cools a warm 496 B well. Partial pics attached.
