Adjustable radius arm bushings ?

Found these at the Graveyard.

I am wondering if anyone has used these and what type of results.
I did find a video on youtube but the guy didnt know what to do with the metal piece that i think is used to lock the bushing in some way.What you see is for one side.

I am planning a complete bushing replacement , 1.5" Ford coil spacer ,Adjustable C/C bushings , Stock or Explorer coil springs in my 87 Bronco II.
The Explorer springs should add .5+ , coil spring selection will depend on how the rear Explorer springs work out.


It is not stated if these are rubber or poly , if these are rubber it would be a no go.

Think there is any benefit ?

The metal Piece is a locking tab. You put it there to lock the bushing in the position you clock them at.
