    Perfect Fit
    Fairly easy install. I put the front end up on jacks and removed the passenger tire for ease of movement. Make sure to loosen the exhaust line at the mid-frame. Don't chance it, use new gaskets and use plenty of break-free before loosening the bolts. Take your time. You'll do better with narrow sockets. Snapped right into place with no issues. I have that weird All Wheel Drive model, so I was a bit nervous about the fit. Worked like a charm.

    Acceleration Back
    Made the 97 a new truck, accelerated better than ever. Bolt on part but didn’t match perfectly so had to increase bends to fit but the end result was worth it.
