After reading about radiator options for fox mustangs on corral, I decided to try the griffin universal 31x19. Its a tight fit, but dropped in my car on the stock mounts. I did have to bend the a/c condenser lines a bit, and work the hoses on as the connections are larger. Hard to argue with for the price though, and the mustang guys claim awesome cooling.

It doesn't have a trans cooler built in, but I've been using a large external for awhile now so it didn't bother me any.

For a griffin that's a steal of a price if you can make it fit
