If that is a flex fan, add a stock 7 blade fan to your list.
Might research doing a switch to electric fans. May be cheaper then obtaining the proper parts to restore the OEM cooling setup.

My current fan has six blades and I don't see how one more blade would make a difference?
I have run a 93' Chevy 5.7 with no thermostat and it run fine but I put one in anyways because I was a lot more comfortable knowing it was there.
