GNS Carbon Fiber Core support Braces              #20000GNS

 

Made out of 100% Carbon Fiber, very light weight yet very strong! The fender braces triangulate the radiator core support to the fender. By resisting the bowing forces, core support bars are designed to oppose the weak link in the sheet metal. As long as the bars are perfectly straight in tension, they are effective!

Metco Drive Shaft Loop                                         #MDL2000

 

Metco's one-piece driveshaft safety loop is custom-designed to fit the floor pan of the 1978-1988 GM G-Body.  No drilling is required for installation.  Like all Metco loops, the ring is made from seamless DOM steel in an oversize dimension to accommodate lowered vehicles and aftermarket driveshafts.  The loop is physically the largest ring that will fit the G-body tunnel at 6.50" OD.  The flanges are laser-cut from heavy-duty steel and the assembly is precision-welded in a fixture.  The finished loop is powdercoated black and packaged with installation instructions and high-grade hardware.

This is the original bolt-in G-body driveshaft safety loop.

DSE Front Chassis Brace Kit                                           #034001

All necessary hardware is included.

Buick Regal Wheelhouse Patch Panels                #20120RH

 

These wheelhouse patch panels are exact reproductions of the original GNX patch panels that were installed on each GNX back when they were produced. These were designed to add additional clearance to the back of the front wheelhouse for the bigger wheel & tires.
Depending on what wheel & tire combination you have you may need additional clearance for the top portion of the wheelhouse, this additional clearance can be achieved by purchasing the "Wheelhouse Extension Kit" that allows for more clearance in the top portion of the front wheelhouses.
We have learned that the holes may vary from GNX to GNX so if you are buying these for a GNX the holes will be left blank so you can trace the holes from your exsisting panels over to the new ones. If this is for a Grand National or T-Type then the holes will be in the patch panels for you!
