My radiator is the sirroco radiator made by Griffin and sold through JEGS for about $221. Probably the same exact one as yours. I'm putting the stock oil cooler right next to it. A few weeks and the whole works will be on the plane so that I can take some photos of where I'm headed with this configuration.

The flap is 18 inches wide by 18 inches long,with a 90 lb gas spring strut to hold it open and a 2 to 1 cable and pulley arrangement and a ratcheting wheel with a another 2 to 1 mechanical advantage to compress the gas spring. The flap is constructed just like the flaps and ailerons.

I'm going out of town for Thanksgiving, and have to work until then, but will get some photos at the soonest opportunity.
