I just ordered replacement carpet for the entire car? I haven't pulled the old out yet? Do you need to glue the new carpet in or does it just "plop" into place and held down with the bolts from seats and such?

I do all my carpet custom. I am a flooring installer of 8 years. I use 80 oz. Plush interior carpet lol. but that is more than just a bit overboard. Only other cars ive seem with my kind of carpet would be like a Maybach. Any way. A can of P90 3M spary adhesive wouldn't hurt. They are about $9 - $11 at Home Depot. It is what I use when I cant get ahold of my trade specific stuff. Look for a spray glue called Misty. Get that if you can.

If you really want to go nutz! I put a hardwood floor in the back of a 1982 VW Rabbit. Laugh if you want, it looked good.
