If you have a GTA  TA or some of the Special Edition Camaro Z28's with the Girlock performance rear end this is the brake hose for that application.  It also fits the '89 Indy Turbo Trans Am (also known as a Corvette eater in 1989....... !!..:-)

The hose is different then the normal production rear disc brake hose.. this RHS is only around 7.75 inches long - quite short..... . the image is correct

This is the RHS.. US Passenger side.  the LHS is lightly longer.
