1972/69 Dart Swinger

I'm having a heck of a time with room for a fan. Check out the pics. I got about 2.5" between the bolt heads on the water pump and the radiator. (looks like 3" in the pic, but it's the angle) The crank pulley extends about the same, but I plan on sourcing a 2 groove pulley, which hopefully gives me a bit more room.

Did anyone else with a BB swap have this issue? A conventional fan with clutch is pretty much out of the question (which is what I wanted). I ordered two spal 10" electric fans which I thought I could perhaps offset a little to clear things. It doesn't look doable.

I'm considering a flex fan, but really don't know how much they extend past the water pump face towards the radiator.

You can see the gap between the radiator and support. It about 1/2". Considering finding away to modify things to push the radiator forward that 1/2".

Ideas??
