Hello. I have had a lot of [older] Mustangs over the years but I just bought a 01 Coupe. Trouble is it is damaged on the left side and I plan to use my 25 years in the autobody trade to fix it.
My question.... I need a section of the left rocker panel. Does anyone know what years will fit? I know the Fox chassis goes back a long ways. I am not speaking of the plastic cladding covering the rocker panel. I am speaking of the metal outer rocker panel itself. THANKS

 

I would assume anything 99-04 would work. Welcome!

 

Welcome to the forums, and best of luck with yuou car. I would call a big recycle lot. You might buy from them anyway, and they always know what years cross. This should be straight forward for them, since Mustangs are a popular, high volume car.
