LUG NUT PROBLEMS and Tools Needed for SUS, WHEEL, Brake Install

OK, i need to install my suspension, brakes, and wheels.

First what size is the stock lug nut. I tried a 21mm but was to small, is it 22? ( i don’t have a 22 so i want to be sure before i buy one)

Also, i will be needing new extended studs, whats the proper specs to get for my 240. And where to get? Anyone local?

How hard will it be to remove my brakes and hubs? what tools are need for the job.

Just want to make sure i have everything before i start

stock lugs should be 21mm (or 13/16 iirc) they could be swollen though

yeah thats probably the case, cause i also tried 13/16…

Any ideas what to do? I was thinking of torching them.
