I don't have the tools, space or coordination to do so. If I couldn't find anylopen ended, factory style lugs, next step was to take them to a machine shop.
I had a Celica that had the same lug nut style. One day,onee of them got jammed in a socket. I managed to get it out but the top part of it remained in the socket. Seems like the threaded nut portion has a cover wrapped around it to make it closed ended. I guess best comparison would be like a condom. Seems like it'd be a nightmare to try and remove all 16 of them unless I just go full torque with an impact gun and a spare stud.
