Restoring my 1971 Citron Yella duster

Check out Auto Metal Direct.
The quarters are available for '72 and newer, so you'll have to change the marker light holes, but not a big deal.
The fenders are available.
The rear tail light panel is available for your car with no modifications.
Did you mean trunk lid or trunk floor?
The trunk lid isn't available, but the trunk floor is.
The parts are kind of expensive, but they are the best you can get and fit well.

As for shipping, maybe find a dealer near you and they should give you a break on the shipping if you buy all of the parts at once. (use the AMD dealer locator close to you on the internet) or contact Summit or Jeg's and they might give you free shipping.

Good luck on your project, here's a link to their web site.
