Roof replacement on a 1970

I need to replace the roof on a 1970 but having a hard time finding one in good shape. Need to replace inner and outer together where the quarters meet and some point on the A-pillars. What are the differences on a 75-to 81 vs 70-74?
Is the inner and outer roof the same at the quarter panel- rear window?
Is the headliner, visor and dome light the same?
Has anybody done this swap?
Thanks for info.

 

I need the one with inner supports looks like the one from ss396 is what i need. thanks

 

well i got a good roof of a 78 after checking it out there is a lot of differences in the 2. The 2 big difference is the seat belt area and headliner trim piece above the doors. Think i will use this one and cut out the piece i need. Mine is rusted under the chrome that holds the weather stripping for the driver side window. Has anybody repaired this piece- Inner roof from Quarter panel to the A-piller where the roof panel is bent over. The worst part is the very back corner where the quarter- roof- window all meet. Thanks for any help

 

John thanks for the link. That showed me what the inner roof looks like and how it is all attached. I think with my 78 roof i can repair my inner roof at the B pillar then put a new skin on. So my next question is which roof skin to get i see the AMD is a "X" part number and there are some out there that are cheaper, is there a fit difference on the roofs. I can get a AMD or Goodmark they are close in price or Jegs has a Gold Star for $100 less anybody have experience with the gold star? Thanks for the help.
