I'm looking to buy some covers from a PIP. Does anyone know if there is a difference in the covers? Clazzio site shows 2 different part numbers for PIP vs non. Everything looks the same except I think my vent is bigger. Should the side piece cover the vent at all? Also anyone know how they fit over the softek? Looks pretty good over cloth. Not sure if their is a difference in the fit. Anything would help. Thanks
