For the price its not worth messing around making your own brackets. These fit fairly well and are made of malleable steel, hence they are easy to tweak to get the fit just right.
These fit just right with a factory style 3 row in my 66 coupe. They mount to the forward most flange of the radiator and then stretch around to the rear where the shroud mounts. Not sure why they didn't just make some that mounted to the nearer flange, but these work just fine. Was going to fabricate my own. But for the price, I decided not to fool with it. I used them with the shroud: FANS1 and had no problems.
