You'll know more once you get the old one off but if everything is in good shape, it's simply a matter of carefully drilling all the spot welds, melting out the lead where it meets the quarters and pulling it off.
Probably ought to get it off before you order the skin so you'll know what else you might need. Mine had alot of rust under there and in addition to making multiple patches, I had to order the gutters.
Make sure if you have to replace the gutters you take lots of pics before removing the old ones. As much as it seems pretty straight forward wher everything goes, it becomes a little less clear once it's not there anymore!
The AMD skin fit on mine with very little manipulation and it was smooth as glass. Don't forget to put the anti rattle goop between the skin and center brace. I got it from a local paint supplier and he let me borrow the application tool too!
Look at my car in Member projects for more details.
Good luck!
