Will either part fit my car?

Only if your car matches: A fits 1967-68 Ford Mustang, B fits 1992-97 Mercury Grand Marquis sedans. Neither part crosses over to the other vehicle.

B's stainless steel resists rust and dents better than A's aluminum, and its 3M tape bond is described as water tight. A's aluminum can dent and its polished finish needs care, but it is a factory-style part.

Is drilling required?

A includes rivets that need drilled holes, plus plastic clips for snap-on mounting. B needs no drilling at all; it uses pre-applied 3M acrylic foam tape.

Which gives more coverage?

B. Its 12-piece kit is 4.75 in wide and runs full length from wheel well to bumper. A is a two-piece molding 3-3/4 in wide and 76 in long.

Can I remove them later?

A comes off by removing rivets or clips, which is straightforward. B's adhesive bond is harder to remove cleanly and may leave residue.

Is one worth extra money?

They serve different cars, so price only matters within each fitment. Check current store prices for each part before buying.
