Do IRS rear springs off a VS commodore sedan fit the rears of a VT series 1 sedan? And do the front springs off a VS sedan fit a Vt series 1 sedan?
Im pretty sure all irs springs and shocks are the same well shocks I know are as for front springs im sure there the same just the strut is a bit different.
There was a similar post re. this a month or two ago. I can't remember who by so a search will be required. Factory standard type rear springs (IRS) are definitely different between VT: # 92048208 sed and VR/VS: # 92045631 sed. VT wagon are # 92048211.
the fronts should fit as i have fitted VR struts to a VT on the front altho they are a bit shorter and leave some play in the strut. will work but not the best option to go with.
