Any difference in the mounting points / speaker connectors / window switches (etc) between S2 and S1 door cards?

In my quest to make my car slower, heavier and generally less-cool, I'm piecing together a leather interior and I found a cheap set of leather door cards from an S2. I have an S1. The mounting points and connectors look the same, heck the door cards themselves are practically identical except for a padded arm-rest and some different accent lines... just wondering if anyone has tried this before I take the $50 plunge on these panels.

Thanks

Ryan
