Will the boot cover from an 02 sebring convertible fit 05?

It's unlikely a boot cover from a 2002 Chrysler Sebring convertible will fit a 2005 model. While they're the same generation, there were likely subtle design changes over those three years that would affect the fit of the boot cover. The shape and mounting points could be different enough to make it incompatible. It's best to check with a parts supplier or look up the part numbers for both years to compare.
