I haven't got that far yet.....you may have to modify your rad support to get the fenders to fit right. It looks like the stock rad will be too tall, you may have to cruise the junkyards. Late 70's Ford pu w/6 cyl had a narrow radiator......some guys use a Dodge pu rad in their F-1's, looks shorter than the stock one...... Also early Mustangs (65-66) use a smallish rad, you can get those repop....
Using the stock 47 radiator on mine. My 350 Chevy never goes over 180 degrees,even on the hottest days. Put the biggest pusher fan I could find in front of the radiator, under the shroud. Only nice cool air going in the grille/radiator. Baron
i used a 1 ton dually aluminum radiator bought at swap meet converted cross flow to vertical flow. cut off filler neck and rewelded it fabricated fan shroud ,used ford electric fan from f 250 for my 500 cad engine
