No worries, figured that is what you were referring to but wasn't sure.
You can get the liner on Partznet. In looking at their site again the have "fender liner" and "apron assembly". Not sure which would actually be the part you need. Might want to shoot them an email just to check since they don't have pic's with the product name. The apron assembly is almost $400 bucks but if it is just the liner that you need it'll be about $100.
