I have done this to my '71. Bought the new "skins" from Legendary. It is tedious but can be done.
1) originals had the innermost window wipers stapled to the steel. I do not have the capability to staple through steel so I used black rivets from McMaster-Carr
2) you will need to re-use the "teeth" punched in the steel to secure it to the fiber board. When you separate the two you will see thar you will need to straighten out the teeth to be effective.
3) there are several locating holes on the reverse side to get the alignment close.
4) you will need small c clamps and spring style clothespins for clamping while your contact cement fully dries. use trim adhesive spray and brush.
5) when going "around the corners" you only use 1 thickness so when you fold it so you are not pushing the panel away from the mounting position. I think that is what the factory intended so when you examine the originals it should be apparent
6) measure and or mark the original locations with a sharpie.
7) this took me about 1 month to do. Not being in any rush.
8) Window wipes were top cat brand and fit perfect.
9) a lot to do but I believe you are up to the task.
10) I am sure you will have more questions.
11) start with the rear panels, they will be a bit easier, because of the window wipers being smaller. Much luck
