Which style carpet and how does it compare between suppliers?

How does this sound?

1. Put down my own sound deadener.
2. I'll order the 500 series 80/20 loop, nothing special.
3. Let it sit in the sun, or use a heat dish contraption (my wife bought one to use in the mornings when its cold and didn't want to turn on the heater) to soften the carpet
4. Glue or Screw (where appropriate) the high spots of the carpet that don't sit proper to the deadener.

What after market floor consoles are available for a 65 dart gt? Do I need to have any specific provisions in place for one?
