Massive PREMIUM High Strenght Panhard Bar / Rod Mounting Hardware Kit GM F-Body Camaro Firebird V6 V8 1982 - 2002 massive MAHW'16706 Massive's NEW hardware replace the now discontinued GM panhard bolts on your F Body. No, you cannot just run to the hardware store to replace your originals, these bolts use a "shoulder" design, helping to locate the bar properly. Regular bolts would either allow the bar to move (too small), or require you to DRILL out (too large) parts of your frame to fit them. We went with high grade, extra strength steel and plated them zinc and yellow dichromate for max rust resistance. We've include upgraded nylock nuts and discreet washers so this critical joint can't come loose. Great for your restoration, general repair, LS swap, race car, stock, adjustable panhard or any other type of install.
