crossmatch oem part #'s to fastlane part #'s

is there a reference guide somewhere that will cross match oem part numbers with the part numbers here on fastlane and/or ebay. i'm always wondering, (without having to call an authorized dealer), if the parts listed will match, any thoughts?

Greetings Dave,

The part numbers you see on Fastlane are not cross referenced numbers but ones that Fastlane gave locally. I think there was a problem in the past with p/n theft so they opted this method. Their parts do have actual MB part numbers. If you give Phil a call at Mercedes Shop listed on this site, he'll be more than happy to ensure you recieve the correct part you are seeking.
