cchang I did not have to modify the dash beam itself. once you mount it up there will be a gap where the two lower support legs met the transmission tunnel, this area needs a lot of attention because the srs control unit mounts to the same bracket as the lower dash beam supports. this bracket is spot welded to the transmission tunnel. I have not yet addressed this whole dilemma...still thinking about gc822bdreamers suggestion of making an adapter bracket. I want to do it but I dont know if I should snag the bracket off my RS or just machine one at work. more to come on this topic. if anybody can tell me how important it is that the srs unit be mounted EXACTLY where it was or can it be a few mm up down left or right? if I make the bracket its going to be about 10mm higher than before. due to the hardware needed to mount it.
