HELP! Rear quarter/trunk replacement 1st gen!!!!!!

[69MyWay]

Okay guys. On www.projectr517.com we have hit a major hurdle. We were able to purchase the complete trunk pan with shock mounts, tank supports etc, and a new driver frame rail. We also have the inner quarters, rear body panel. We have the outer full length quartes coming soon.

Last weekend we started cutting it up. We already put a new main floor in the car. We cross baced the doors and inside before cutting.

NOW...we need some major guidance, help, links...for the best process to cut the whold back end out. Can somebody point us to measurements, photos, links...or been there done that info to make sure we get this cut and welded back right?????

Hers is a picture as we went in. Right now we have the left quarter off and are not sure how to proceed.
