Rear wheelhouse liners differences

2.7 cars have 2 different parts numbers for each wheelhouse liner panel (front, center, and rear) One set is listed as narrow type 350mm, and other is large type 380mm (assuming they mean wide?)

5.2 cars have their own part numbers with no mention of sizes. There are more used 2.7 liners available and wonder is anyone knows if they would fit my 1997 5.2 car? What are the differences between the early and later liners? Assuming that the liners cover the same square footage, but perhaps there are different attachment points? anyone....?????
