I'm pretty sure that the 97s do not have the shock but have the automatic tensioner instead of the manual adjuster with the shock. Quick check is to look between the water pump and power steering pump for the adjuster. There will be a hollow 1/2" round protrusion sticking straight up (~2") with a 13mm hex on the top portion of it, in a goldish anodized color. If you see the adjuster you should have a shock too. No adjuster = automatic tensioner and no shock.
