Options for installing AMD Quarter on a '70 Dart

I'm just mulling over how to install an AMD quarter panel. I've already installed the driver's side and its all tek screwed in place. There was some lessons learned.

• Its difficult to install a whole panel exactly like the factory did. You're going to have to cut and trim around the roof pillar (at least I had to).
• Disturbing as few factory welds as possible is preferable to me especially where splices are easy to cover/not as visible
• Installing a full rocker is a ton of work so I installed 2 partial sections on the passenger side (turned out well)
• Butt welding on old metal isn't fun and its hard to get a good finished product. Instead of totally cutting out the outer wheel well housing I butt welded in a section of the outer wheel well housing on the driver side. I will overlap weld on the passenger side.
• Leaving the door on until the quarter is fitted so the rocker and quarter gaps can be checked was a good decision.

So now I am humming and hawing about how to fit the passenger side quarter. I was thinking of not disturbing the roof seam as well as the rear window and possibly the trunk welds. I could cut a line along the top flat surface and flange along the gulley from the front of the rear pillar to the back. Has anybody done something like this? Its just an idea at this point....maybe a bad one. :)
