I went to install an Energy Suspension Bushing kit onto my '92 4Runner last night, and found that the supplied 18mm rear bushings were way too small.

Turns out mine has a 21mm rear bar.

I've searched all over this forum and can't seem to find any reference as to that being an option.

Can anyone tell me if this size bar was ever offered, or did someone perhaps swap on an aftermarket bar at some point?

Thing looks factory original by all indications.
