That's actually what I'm putting in. I'm doing sections of fatmat where needed, then a layer of 1/8" ensolite then a layer of mlv.

Mike the work you did on the shift boot and console plate looks great! Nice work.

Good deal. My Sierra is quieter than my sister's lexus now.

I decided instead of powder coating the shifter boot plate, I would make the other plates match. The pictures aren't great, but I epoxied pieces of aluminum sheet onto the areas where it used to be dark grey.

Started on a new switch panel, just waiting on the switches to show up.

I decided to follow this guys recommendations on sound proofing. A lot of people recommended it and I can't say I know better. http://www.sounddeadenershowdown.com/
Layer of Fat Mat to keep the panels vibrations low especially on the rear firewall.

Then a layer of 1/8" closed cell foam covered in a layer of MLV (mass loaded vinyl) This stuff is heavy. I probably added 100lb into the car but it should be as quiet as a new car. I have to pick up some contact cement tomorrow to glue all the loose edges together. Finish the rear firewall and then I can put the interior back in for the last time.

Don knows what he's talking about. Be sure to do the doors and behind the sail panels as well.

Thanks. I'll be dynomatting the doors soon and I'm waiting to do behind the sail panels when I put the stereo and speakers in the car. I don't think I'll bother with the foam and mlv on the doors.

It's definitely worth it but it all depends on just how quiet you want the car to be. My truck is my daily driver and it has a nice stereo. I wanted quiet so I did as much as I could.

Yay, I have interior again! I think the front seats have been in and out of the car 10 times on this conversion, hopefully they are in for good now.

Next project is the trunk. I'm going to seal up all the holes. Install a removable panel over the fuel pump hole and spare tire well. Finish up the rear wiring for the fuel pumps and battery disconnect. Repaint the rear cage down bars after removing all the other tubes. Then install a nice thin black carpet.

Looks great Mike. So, how close is this to being on the road?

Still a long way. I'm only getting one day a week to work on it. I still have to run fuel line (stainless hard line), make a crank pulley, fix a coolant leak around my belt drive, rework my intercooler charge tubes, wire most everything, shorten my driveshaft, fill and bleed all fluids, alignment, hang the exhaust and build a new air intake and filter box. Hopefully it will be done before spring is here, but I'm not rushing it.
