i have a 07 C180 and think a RXT or RXP intake grate will fit on it. it has three 10mm bolts in the rear with the center 1/4" ahead of the outer two which are 2 3/8" apart. the front 13mm bolt is about 16 1/4" in front if the middle rear bolt. looking at pics they look the same, any one post measurements of a RXP or RXT. anyone have a stock RXT or RXP they want to get rid of ?
