Radiator advice

IMHO...

find a stock copper brass heavy duty /AC radiator. Or at least a HD cooling stock aftermarket. Be sure you have all the right pullies and the correct HD ,/ AC cooling water pump.

As for fan be sure you get a fan designed for AC / HD and stock shroud.

if you go with stock parts for the ENGINE and HD / AC cooling radiator you will be in good shape.

It is a basically stock engine and a manual trans to boot.
