rear anti roll bar to fit an S

[magpies]

I'm looking to use my S2 (in the process of fitting a Cossy 24v/MT75box, rear lsd 4.27:1, rear discs etc.) in light competition sprints/hillclimb/smooth tarmac rally as well as B road hooning.
I've fitted bilsteins from a Griff with adjustable platforms along with 500lb springs front and 375lb springs rear. Now looking to lessen the rear roll so my question is will a rear antiroll bar from a more modern TiV fit my S?
