I used a Rabbit/ Scirocco rad in my 1200 race car. Had to use a piece of tube to transfer the water from left to right under the fan. Rabbit/ Scirocco rad is double pass all aluminum with plastic side tanks. Worked great. Needed to make custom mounting that consisted of a piece of aluminum flat stock across the bottom of the rad mounting to the front inner frame and some upper brackets to hold the top to the rad support.
