Ok just attempted to put the chrome door trim/lock cover(s) on and THEY DON'T FIT. Well they do but they're to small, the SLKs door are thinner than the crossfires. There is a 3/4 inch gap between the chrome and the edge of the door. All the bolt holes line up and everything else is great except for the gap. So i'll be returning them on monday.
Still would like some input on the gauges... thanks.
