6-71 & Mechanical Fan, and other questions.

Much appreciated, that looks about the same depth/thickness as the Stainless fan I'm running.

I've got a 4-core C-body big block radiator in my '74 Duster, and have about 3/4" I could use to move the radiator (gap between the radiator & core support). If I move it, I might be able to keep my Shroud if I use a 2" belt.

3" would require me to remove the shroud and cut away part of the core support to relocate the radiator even further. I think, anyway. I won't really know until the 6-71 is sitting on top of the 340 and I've got a belt hanging from it. which is why I figured I'd ask. wouldn't want to order the 3" setup, only to find it wouldn't fit.
