On that cowl bar flat stock, i think it goes about the middle of the cowl bar, at least by seeing the paint lines on mine as to where it went that seems to be it. I will take a picture, and also measure my other one that has not been modified and let you know the sizes,
afternoon update, I had this used electric fan that was way too big to fit the radiator, I looked in summit catalog last nite and it seems like I was going to need one that cost at least 150.00. I went out this moring and remeasured and decided to cut this one up I had and remake it to fit this radiator. Seeing as how it has 9 blades and was very wide I am going to guess it will pull enought air.
this is the pic prior to modifying.

I like the way it turned out, the shroud is pulling from nearly every row and coil. Cost for Fan free as it was junk inventory, cost for epoxy glue to reassemble was $20.00
While epoxy was sitting up I made some rear straps to weld on the frame so I could have easier access for something to secure to for trailering.
