Recognize this fan?

I swapped out the dangerous metal radiator fan on my 1974 FJ40 to the larger 8 blade plastic fan (I think for an FJ60). It works great but it is LOUD at higher RPMs.

So, I am going to switch to the 6 blade plastic fan. The one I have looks a little different than the current OEM fan part number 16361-60090. Specifically, the new OEM fans do not have the notches that the one I have does (that I circled below). Does anybody know what this fan is from? Is it okay to use vs the16361-60090.

As always, thank you for the help.

It is still going to be pretty lound since it is a direct drive fan. It'll make the cruiser scream at 55mph, just not as much as the 8-blade fan. If you want it to be really quiet, switch over to a fan clutch.

As for the fan that you have, just simply putting it onto the water pump for fitment and checking clearance from the radiator/fan-shrowd should be enough to determine if it will work. Looks identical to the oem fan that I have except for the notches (as you mentioned)

Does the back side look identical to the oem? Could it be an oem but warped possibly from being stored in a bad place with heat? All though the bumps do appear to be rather symmetrical. Here’s some pics of the back side of two have.
I got the 8 blade fan after seeing yours and I'm still tweaking a custom shroud I made for it and a Champion aluminum rad. Since I only wheel at low rpm I don't think I'll be bothered by any additional noise. We'll see.
