Thanks for looking at my build. I ordered the radiator from speedway motors. The part number is 917340-28.

Not sure yet on how it is going to work. I am waiting for the radiator hoses to try it out. The only issue so far is that the lower hose is going to be short at an angle of about 45 degrees. Will have an hpdate in a few days.
