Okay so I've been meaning to do this since I got the car and finally getting around to it now. I have sourced a spare a pillar trim piece and a boost gauge pod (that is not even close to fitting) I've seen a few people asking about these so thought i would post this and hopefully it will help someone. First of all I offered up the gauge pod to the area I want to install it and got a rough idea of what needs to be trimmed from it. Which as it happens is all of the base plate. Then cut out a section of the a pillar trim to allow it to recess. And from there it is all trial fit and trim a bit more until it fits as close as possible to the location I want. I want to to recess in a bit so have also cut out a section further into the pillar trim in front of where the gauge sits so I can mould a tunnel detail into it (hopefully this will become clearer with the photos and as I progress) The work so far: The next stage is to fibreglass it into place and add a skim of filler then smooth and mold it in. The only real hurdle I have now is finding some fabric to match the trim to cover it with. Anybody have any spare?
