Here's a spanner in the works
I used a series 2 b/b in my racecar. I removed the 2 side frames and replaced them with flat channels containing a captive nut. A couple of channels on the bottom rail for it to locate in and a couple of brackets to fitewall. I don't run any fan (due to no standing in traffic ) and it runs at about 175F no prob - and it is a stock core!! Any thing is possible - also talk to your local radiator bloke with the car or dimensions and he probably will sort you out in a flash.
Cheers
