I have given up on that self-mutilation fest for now.
I have 2/4 seats done.
I was just out removing interior panels to see where I can put sound insulation.
You can fit the insulation pretty much everywhere. I would recomend spraying the floors, rather then lay mat.
I found a leak somewhere is bringing water down into the cab.
Probably the roof seams.
I also removed the rear door panel on the passengers side, and I'm trying to determine why the door lock isn't working automatically.
If its an electric lock the cable usually is what is getting hung up. Sometimes the acuator fails, and then once and a great while a relay will go.
