Auxiliary water pump

The blade numbers shouldn't matter, they are all inside the case of the fan enclosure. Looking around, not seeing anything that thin. Think i found the Spal you have, its very thin, but only 8.5 amps. It isnt moving much air at all.
If you can find an extra 1/2 clearance, there are definite choices.
Seeing now what you have, i would bet money that is your issue. Can you move the radiator forward at all?
I have never ran a pusher, not sure if that is a viable alternative

Spal 30100400 amp draw is what I googled and yes, 9 amps is it. So it doesn't see strong enough to do the job. Too bad, it got good reviews.
My radiator is right against the support so no movement there. I have the trans cooler on the front side of the radiator so I cant really do a pusher style without reworking the steel trans lines I ran to the cooler. I'd also have to rework the hood latch framework too, but after all that, I could put a large fan in front.
But, after saying all that, I see that summit has a bunch of 3" think high amp fans with shrouds. I posted a question to them to see if they can really verify that the total thickness including shroud doesn't exceed 3 inches. We will see.
Derale High-Output Single RAD Fan and Shroud Kits 16821 for example should work as long as the thickness they say is overall thickness.
