Hi Peter,
you are right it needs improvement. But I can't recommend to work on the Airbag w/o testing afterwards. This testing is very expensive. We have in our company an Airbag Shooting Center. First you need to know the exact cutting line of the Airbag door. Then you need a laser cutter and could do a leather wrapping on the Airbag. Then we need 4 Airbags all wrapped and laser cutted in the same way. Three test shoots and one left to build in when everything is ok. Please consider 5000 € for each shot and you have to buy 4 Airbags from MCC. What I would like to say when money is not a problem you can change the Airbag area but I would'nt. I will attend on the Thrill of the Hill Event this year and when you like we can met us there and discuss if there is a possibility to improve your dash w/o so much and expensive changes.
