Diff Bushes - the same for GKN or BTR?

[RedCabbage]

I am about to replace the diff bushes on my '94 Chimaera.

The diff is finned therefore GKN. Are the bushes the same regardless of which diff is fitted?

Some bushes have different flanges - My GKN side bushes kind of float, rather than being captive. The centres are also a different diameter IIRC.

Clever trevor has come back to me saying he has some in stock but isn't clear if they are different.
