I would be leery of the fan, myself. If it came loose, and flopped around, chances are it has some damage.
The fan clutch might have been loose internally, and caused the wobble/imbalance that caused it to snap...hard to say.

Thinking of changing the WP just in case. The fan blades seem to be fine, going 45 mph at the time.

Back in '75, I replaced the water pump on my '71 240Z.  Driving home from my brother's place, I heard a bad noise from under the hood.  Pulled over, shut is down and popped the hood.  The water pump shaft had sheared off, and since the fan was pulling air, it "flew" into the radiator.  Had it towed and called Beck Arnley, the water pump brand.  They ended up paying for everything including the tow.

what is the thought on flex fans, when my clutch fan went bad I installed a flex fan no problems that I have noticed

Personally, I don't like flex fans. I've had too many of them flex themselves thru the hood. I've used both the stainless steel/metal blades, and the fiberglass blades(name brands, not cheapos).....and have had both types fly apart at high rpms....such as on a missed shift. Even without the high rpm runs, they tend to fatigue from the flexing, and eventually just break.
This is just MY experiences with them...lots of folks run flex fans with no problems. Plus....they're noisy as heck!

Sounds like a good excuse to go electric!  (Unless you are trying to maintain originality...)

It's all original, took the WP off today with the pulley still on it. When I spin the pulley you do see a little wobble, going to change the WP. The WP was changed a few years ago to aluminum. Should I replace it with another aluminum WP or with cast ?

Installed new aluminum high flow water pump and new fan clutch today. It's back on the road , seems to run cooler than before and the the rad is not leaking.
