Email your address and I can discuss what I did with mine. Yes get "Air" or you will be sweating your butt off and sitting in your house in the summer waiting (at night) for the temp to drop below 100 at 9PM so you can go take a ride.
Mike is right about getting your top as insulated as possible around the edges. You are going to loose a lot of air around the side windows and windsheld areas and out the back and around your doors if you don't. Vintage is about the best.
For sure get the largest radiator you can fit and do the
oil cooler thing too. I am running about 190 but it quickly goes to over 200 if you are driving in slow traffic.
I was driving up Scottsdale road when the traffic was stop and go. Well I got home and my lower lip had dried up and peeled right off my face.
