dart roof replacement

just picked up a 1970 dart swinger. super clean and straight car with very little rust. unfortunately it had a vinyl top and has some bad damage underneath. I can easily locate pieces to replace the rust damage below the rear window. the car has holes in the roof just above the front windshield. I cannot find patch panels. I can make them (its a lot of work) but was more interested getting a new roof skin. my searches have found just about every roof skin except the dart swinger roof. does anyone have a source for one? thanks in advance!
