Need links/ photos/ tips on roof replacement

Some time ago I bought a 74 Scamp, slant, VINYL roof, and the roof is badly rusted and leaking/ bubbled under the vinyl. I just located a very much junked 69 Dart HT and am planning on dragging it home for the roof, and 'whatever else.'

I don't know yet how much of the roof is "that bad." The entire thing shows bubbling under the vinyl, and I'm thinking the rear/ C pillar/ rear trunk deck is a "for sure" replacement. Any photos/ links/ tips you can give me, helpful. I'm off to read the later "body" manuals hoping to learn a bit there. I won't myself be doing this, hoping to "scam" the neighbor into it LOLOL
