Yeah, I've been working on putting the box back together, which is all of the electrical and stereo wiring. Cleaning up some routing and hitting the connections with dielectric grease along the way. Messing with the speaker set up too so haven't been in a hurry to put it all back together.
As for the noise/heat shield, I looked into it, shipping cost is anywhere in the U.S. for $20. Yeah, buying a piece of rubber that small is hard to find and expensive. You could get two of these out of a 10' x 10' pc and that's $100. I paid $36 for that foil carpet and that was for a 3' x 4', this is bigger than that. I have two different types of rubber, both will last forever but one has cords you can't see running through it. Can only be bought in a roll and it's over $1300. My plan is to cut a new one for myself out of the reinforced stuff and fine tune the cuts even more, this'll be the 3rd one now. If I'm putting my name on it, it's going to be close to perfect or it doesn't leave. I'll post some pics of exactly what you'd be getting.
As for cost to the customer, I'm at $70 to your door?
