Just installed the first of my new parts today. Nothing fancy, but it looks very nice. I bought the BMW underhood insulation from Mobile Tradition. While it was expensive, it is done, went on perfect and will last a long, long time. Anyway The paper backing is an exact template of the insulation for those that might want to roll their own. I will send it to the first guy that wants it, then I ask you to send it to anyone else who shows interest. It will save you some time if you were to make your own and it will be exact.
