While trying to install my speakers, I found the pad under the carpet soaking wet. I pulled it back and I don't think it rusted through luckily. I'll figure out what happened and fix it, but my question is... The stuff that is ruined, the pad (looks like insulation of some sort) and some type of black vinyl, where do I find replacement for that? On LMC's website, I see sound deadener and heat shield materieal, but doesn't appear to be the same stuff by the looks of it (different color and materials) http://www.lmctruck.com/icatalog/cc/full.aspx?Page=89 I'm really OCD about things being "correct" so is this what I use to replace my old pad/barrier with?
