I'm in the process of converting my '71 Challenger with a 318 to a (stock '72 block) 340. As I was removing things from the engine bay, I notice what appears to be a tiny pinhole leak in the (22 inch) radiator. I obviously need to do something about it, but not sure what? I'd love to convert to 26 inch, but that's a lot of work for what I'm planning to do with the car for now. There doesn't seem to be any original repro radiators out there, only aftermarket and I'm not sure if the aftermarket ones will accept the fan shroud brackets? Another option is to shipping my original off for restoration.

What has anyone here done in similar situations? I'm all ears!

Thanks!
