I cut out the holes for the bodyplugs and will install those later.
Anoter piece of insulation goes under the dash. I bought it as an original repalcement mat, that looks somewhat like it's made of compressed old rags. This is one of those pieces that won't be seen later, but hopefully will add to the overall quality of the car by keeping noise and rattles away. It took me a while to figure out where exatly the padding is to be located - only after I took out the original piece, that I had luckily not thrown away yet, was I able to install the pad correctly.
