Thanks I have the old booster one for a template, for the upper piece i am hoping it is the bmw version - looks like it - should be for the $$$when i got the upper firewall insulation from W+N a few years ago, it was the BMW part ... so hopefully it still is. if you want the pattern of the original BMW part, i can trace it for you. you will have to fit it to the CS Werk piece as they are slightly different
