Spindle nut tool for newer style nuts?

[1 Patriot-of-many]

I haven't checked my spindle nuts yet, but have new washers and 4 newer style nuts to replace once I start. What spindle nut socket fits these 8 notch nuts? I'm guessing a normal 4 notch socket will work but don't even know which one will fit them either. Suggestions where to purchase and which? Cheapest is better of course, It will probably be used only 4 times hopefully! Thanks!

I bought a surplus one on eBay around 3 years ago.
Borrow one from your local motorpool?
