How to Install a Pontiac Grand Prix Strut Tower Brace.

The GM part number is 12456148 for 1997-2003 W body cars. This item came on the Monte Carlo SS and Regal GS. The brace "kit" comes with all attaching hardware. This same brace will also fit on the rear strut tower by elongating the holes.

If you have a 1991-1996 W-body car purchase a strut tower brace for a Cutlass Convertible from your GM parts dealer (sorry I do not have that part number).
