The AMG style rocker panel was a lot of work. The fit was off and I ended up doing a hell of a lot of cutting, fitting and fiberglass work. At the time I was determined to get it done because of how few of these panels were available. And I did finish it to perfection (took my time) after figuring out how to remove the original OEM panel. No body shop near me would touch it. I don't have any idea if the AMG panel that fits is available now. Is it?
I have since sold this crossfire and regretted it ever since. Although I ended up with a 2002 M5 I would still rather have my crossfire. I put quite a lot of engine performance upgrades, lowered the car, custom exterior parts and on and on. It really tore *** with the engine mods and computer mods.I really miss it. I will say it was a very firm ride with the it lowered. hard on the prostate.
Anyway it can be done for the cost of the panel and fiberglass, bondo and your labor. Then that cost to me was a total of $225.00. Good luck, sorry I can't help you more.
