Adjustable?
What is adjustable on them?
Am I thinking of the same thing here? To me a radius arm is the large cast
arm on the rear suspension. I can't imagine it being adjustable.

Got it now.
21A450 is an adjustable front suspension tie bar.
21A392 and 21A393 are right and left rear suspension radius arms. Mind you,
some call them swinging arms. The BMC workshop manual uses the term radius
arm but it's up to you.
There have been 3 types of rear suspension radius arm during the production
of the Mini. The difference is in the bearings. The later ones with bearings
at both ends of the shaft are the best and probably the most common now.

NO

21A450 is the standard tie bar

and

21A1091  is an adjustable type.

Both are front suspension tie bars
