the rear beam on a 2wd saff cossie is a granada one, the rear arms are cossie only, the abs sensors are granada
shocks and springs are all the same fitment only poundage and damping rates vary

cos diffs are 7.5 inch with slipper, normal is 7 inch i think, no slipper, ratios are vehicle dependant,

all the 2wd cossie stuff will bolt onto any sierra bodyshell
