I almost forgot, there is a new product on the market.
Slim Fit RadiatorsFrom the manufacturer: Slim-Fit Radiator Systems are only FOUR INCHES THICK. That includes the radiator, shroud and electric fan combined! This amazing engineering feat was accomplished by inventing and integrating a patented 3rd tank directly into the radiator core. The fan motor is then mounted into the special 3rd tank to eliminate all the extra hang-off from traditionally mounted fan.
Hopefully, they come in a size we can all use!!
