I've informed them of the problem and will be returning the fan. And I posted the problem as a review on that page. I've ordered a much thinner one in the hope that it will fit the shroud that came with the kit and will clear the water pump.
I have a 4-core Champion radiator in my 1966 vert -- stock radiator opening, stock radiator height and width, no mods to the bodywork. (I have a 302ci with the 289 layout (input and output of the radiator are both on the passenger side) Since I was installing AC in my car, I wanted an electric fan with shroud.
SYNOPSIS - keep the 3- or even 4-core radiator and just get a thinner fan (it was unclear what you ordered that was thinner -- rad or fan -- don't trade in for a thinner radiator).
Here is my post on VMF with discussion (https://www.vintage-mustang.com/thre...#post-10275657
I got a fan/shroud from Radiators-4-less, but I ran into the same clearance problem you are having -- end of the water pump shaft conflicted with the nose of the elctric fan. In my case, it was about 5/8" overlap.
So I kept the shroud and sent the fan back to the company, and I bought a thinner fan (about 2.5").
They make electric fans that are only 2" thick (SPAL makes one, but heck, there are MANY thin fan makers -- and probably most end up coming from China anyway, just re-packaged.
I also cut off about 5/16" from the water pump shaft using a grinder - cuts easily -- paint the cut off end of the shaft to prevent rust.
I now have about 1/4" clearance between the water pump and the fan, which is pretty common (several responses from VMF indicate that even 1/8" is common).
