At least you have white panels. I have never seen any ginger that look right all splotchy. I have been cleaning up parts for my 72 Q vert. i lucked out bought a crashed car with perfect original interior I just have to put the door speaker grill holes in.
i have two white interior cars and will need soon, I hope.
I went with a complete set of whichever ones Don (OMS) sells (in fact, I think almost my whole interior except for the cut-pile carpet and TMI Sport seats came from OMS). They were not bad to work with, just needed a little bit of tweaking of the factory grab handles to fit properly. They also didn't come with the chrome strip trim that separates the carpet from the vinyl.
Make sure to get the 'long' door panel clips as well (not the 'short ones').
