VY - VZ Infill panel (eBay item 220672691570 end time 21-Mar-11 07:24:42 AEDST) : Cars, Bikes, Boats

but it says it only fits vy/z utes, but i cant see there been any difference between the three..

anyone know what the difference is???

Can't say I know the difference, but the crash repairers working on my brother's car have a VU SS with an infill panel. Might pay to ask a crash repairer, especially if you plan on having them do it.
