How can I tell if its the original radiator or not? Is there a tag or a number stamped in it anywhere?
Harrisons supposedly all may have the "Harrison" brand embossed on the right tank and a "Fill Cold" embossed on the back of that tank. Mine was missing the tag so I picked one up from the Parts Place to be added when I had it restored in May. Note that the lower fan shroud clip arrangement was different between my Harrison and the aftermarket radiator I had been using too.
