Recently replaced my carpet throughout. It came from Zip Corvette.
For the compartment doors, center tunnel sides, center console sides, kick panels and seat backs, I used brush-on contact cement on both the carpet AND the piece with a laminate roller for pressure. (The laminate roller is no big deal--it just makes it a bit easier to apply pressure.) The corners of the seat backs were a bit obstinate and required an overnight weighting but only because they (unlike the original) had sewn-on vinyl edge binding.
The main front and rear carpets all fit perfectly and I found no need for adhesive. Installed during a COLD winter. I did let the carpets relax indoors for a couple days but the garage and car were barely above freezing when I installed.
