Just a little update for anyone else doing this conversion.Had a good look at the brakes today and noticed abs sensors and plugs for the rear discs.Turns out the ST170,s and RS,s have ABS all round.



Had a quick look on my 1.6 ghia and noticed this plug near the rear wheels


I don,t know if it's just the ghias that have the same loom but it seams i just plug it in to the abs sensors on my st hubs and away i go.RESULT.

As above i,m not changing the whole beam.Just swapping hubs,flexy pipes and handbrake cable over.
