When I just had my mufflers changed they removed a flat bar about 3/8" thick, 1.25" wide and 3' long from the drivers side rear to make their job easier but they "tossed" the part! I don't know the name of this part but would say it stiffens the unibody chassis. It runs from the outer edge from where the jack would go on the side in front of the wheel and runs back and in towards the tunnel for the driveshaft. there is one per side. They would form a "VEE" if extended, they do NOT run parallel with the body, front to back. More front to to back while going towards the center the further back it goes. I need a number to get a price or so this shop can source one of these bars and mine were without rust. Anyone help? Thanks, mark
