Restoring interior in 84 5.0

[black 96 gt]

Sorry for my ignorance but i just have a few questions before i start restoring my interior. I have already put new carpet in the car, but i sort of rushed it and never bothered to flatten it out. What is the best way to flatten it out? Also, is the carpeting in the hatch of 79-86 Mustangs cut in the same shape as the 87-93 Mustangs? I would assume they are the same, but the carpeting i would like to buy on American Muscle says it only fits the 87-93's. And lastly, where can i get a nice headliner for a decent price? Thanks, Mike

To smooth out some of the wrinkles & help the carpet set in corners, the use of a hair dryer is very helpful.

83-86 uses a different profile hatch area carpet that the 87-93 due to the difference in rear trim panels.
