gotta 79 Camaro, the carpet is f**k'd up so i wanna replace it but not fully sure how to install it or wat materials i need. Help?
Get a gallon jug of Acetone from Home Depot in the paint department. Pull all the old carpet up, pull up the tarboard sound deadening material, then pour out the Acetone and scrub the floor using steel wool to clean up any glue or tar that might be on the floor. Once you've got the floor pans clean, paint them with flat black paint to protect them from rusting. Finally, you can find replacement carpet at a parts store, just glue it down with contact cement.
Changing the carpet is the easy part. Removing all that's holding it in is the hard part. You can google for automotive carpet and order it online. You can expect to pay 120-175 bucks for a carpet depending on who you order it from. (Try JC Whitney) Order the carpet that comes with the padding attached to it. Once you get the carpet, the hard part begins. Take the seats out, and unbolt the seat belts from the floor. Remove the center console and any trim around the edges such as the sill plates that hold the carpet in. Take care in any wiring you encounter, remember where it is. Once everything holding down the edges of the carpet have been removed, the carpet comes out pretty easy. Vacuum up any loose debris then install the new carpet with padding and put everything back in that you took out. An experienced installer would take 3-4 hours since the center console is the hardest part. If you have never attempted this before, expect a full day at best, probably two to complete the job. No other materials are needed unless there are pieces of carpet that are glued to the kick panels in the front. Then a can of 3M spray adhesive would cover that.
