2007 4Runner Sport 4WD, 340,000 miles

Both of my front inside boots are seperated so its time to replace. I had made the mistake of replacing Toyota axle assemblies with aftermarket (OReillys with lifetime warranty). I want to go back to the Toyota axle assemblies.

Checking with Olathe Toyota parts center, 43430-60062 is the latest, and correct, axle assembly per my VIN. Shaft Assembly Front Drive 43430-60062 | Toyota Parts Center
Also, with this latest part number, Toyota requires a new lock nut hwhich happen to be on back order along with unicorns. Nut Lock 90177-28001 | Toyota Parts Center

However, I have seen discussions of guys using the 5th gen axle assemblies in the 4th gens (bolt right in). Reasons why are improved boots and cheaper. Does anyone have any direct experience using the 5th gens in 4th gens?

Thank you and any guidance and direction is much appreciated.
