I didn't do anymore on this over the weekend because I was working on other things, but I bought some aluminum angle pieces and decided to run that down on each side riveted to the side of the radiator. I will mount the overflow tank on that angle piece too, but without the hood I'm not sure where it has to be to clear..

I found another fun problem too. the Street and Performance water neck I referenced earlier in the thread might have to be cut shorter so the lower radiator hose can clear the fan bracket on the shroud. I would really rather return the $100 part instead of cut it so I might try and use the stock water neck. The issue was the bleeder not clearing the air cleaner so I am hoping blocking it off and no other modification will fix it. The stock one is shorter and angles less out toward the fan.
