Rear upper control arm inner bushing

[Stanley]

Piggy-backing on this thread: this may be a dumb question, but is there an upper control arm bushing besides the inner one? I actually can't find a listing anywhere that mentions an outer or upper or something else specifically for the rear UCA. All I see is "UCA to frame - 1 per side" and racecougar's old thread only mentions a single rear UCA bushing ("rear UCA to IRS cradle bushing"). SCP has a UCA bushing listing, and is very insistent that it's the INNER bushing, but doesn't appear to sell any other UCA bushings either. They all look to be the same thing. But then why the insistence on the "inner" part?

There is only an inner, the outer is in the spindle itself.
