All of the exhaust mounts for those years are the same in the area where they mount to the frame, but there are a bunch of different configurations depending on the exact exhaust you want to run. I've ended up having to modify them to hit the mounts on custom pipes a bunch of times. If you can find a stock one that fits with your exhaust, you're golden. If not, they're real easy to modify or make. Just get that piece of threaded black iron pipe out of there, LOL.
