Replacing Sheet Metal – Measurements????

I'm Fixing up a damaged 1970 Cuda.
It was hit on the drivers side lightly, I plan on replacing the parts instead of trying to straighten them out. Basically I need to replace the following;
- Drivers A pillar.
- Drivers door mount area (below A pillar).
- Drivers door rear lock jam area.
- Drivers rocker panel.
- Drivers rear quarter.
- Repair drivers side roof where it meets the A pillar
Are there drawings or dimensions I can get somewheres or do I just start with the rear quarter panel and work forwards?
What I'm concerned with is the front windshield fitting and the drivers side door, front fender and hood fitting alignment.
Any input would be appreciated.
