Best order for panel replacement?

I've started down the road to restore my 68 Dart. I need to replace the rockers, quarters, trunk floor and extensions, inner and outer wheel houses, tail light panels, deck panel. This is my first go around and FABO has helped me a lot. I can't seem to progress because I spend more time thinking and contemplating myself into circles so here's where I need help. What would be the best order to do things? I don't think I want to remove everything at once because then what do I align everything to? But do I take the quarters off replace them to the existing underlying parts, or do I replace those parts, aligned to the old quarter, then align the new quarter to The new parts? If this has been covered previously, please direct me to where, I think I have searched the forum pretty well and have found just about everything else. Thanks for the great information you guys have provided so far and in the future.
PS. If you need parts I highly recommend [email protected] (he is a member here) contact him, he is very helpful, works with you on shipping, and offers great pricing. (Much better than AMD's direct pricing.):burnout:
