The support bracket kit that I got came with two small top brackets that mount to the radiator which in turn mount to side braces. The side brace material supplied was just a piece of 1/8" aluminum stock that needed to be cut and fit as required. After studying the layout for a while, and fitting the tilt shell back on to check clearances, I decided to scrap the supplied top brackets and side braces. I just didn't like the looks of any of it. Even parts of the lower bracket that bolt to the frame rails were scrapped.
Instead, I decided to go with full-length side and top brackets that would completely surround the radiator giving it more support, and also look a lot better. I designed new side brackets and cut them out of 1/8" aluminum.
The next step was to mock-up the radiator support bracket and finalize the radiator location. The bottom support bracket gets bolted to the inside of each frame rail. Because of the total depth of the radiator/fan assembly, it was necessary to move it far enough forward that half of the bracket extended out past the end of the rails. I made two small angle bracket extensions to support the rest of the radiator bracket. Last photo shows the radiator bracket installed. The radiator is tilted back slightly in order to clear the tilt shell.
The fan comes with a shroud that will seal real well around the edge of the radiator, but it didn't fit around the inlet and outlet pipes of the radiator. I was able to cut out the areas using a hole saw in the drill press to make a good fit around the radiator connections. I may have to trim a little more once the hoses go on.
Before going any further with the tilt front, I decided to locate and install the radiator and fan assembly. I wanted to make sure that the radiator mounting brackets would not interfere with the rest of the tilt-front hardware, and also make sure that the radiator would clear the tilt shell when closed. The radiator is a Griffin unit made to fit the Outlaw body & frame, with 2 rows of 1 ½" tubes. The fan is a Flex-A-Lite unit pulling 3300 cfm. I also picked up a radiator mounting kit made by Outlaw to fit the radiator.
Here's the finished rib mock-up, which will stiffen up the shell, mount the grille, attach the hinges and linear actuators, and look good at the same time. Next, the motor goes back in, the radiator gets mocked-up, and then the tilt shell goes back on to make sure the ribs don't interfere with anything.
