Sound Dampening and Carpet

66 Monaco 2dr hardtop

I want to get going on more interior work. Do you guys have recommendations for carpet and sound dampening that you swear by? I recall Big John praising FatMat Rattle Trap, not sure if I want the 50mil or 80mil thickness. For carpet I saw stuff all over the web like stockinteriors and ebay

I also really do not want to wait an eternity for this stuff, as I've heard thats a possibility with interior items. Thanks
