Which RST LSD for a Fiesta IB5 Box
I'm needing to replace the gearbox in my Fiesta Zetec-S as the diff has had it, however I'm looking to uprate the box while I change it all over, however I am struggling to find out if its the LSD from an S1 or an S2 I need.
Can anyone advise me? And also does anyone have one for sale?
Thanks, Rob
