Here's a little custom project I finished up yesterday. I know many of you will probably call me a masochist, but hear me out lol.
So after I installed the aftermarket Kenwood head unit, the Dolby center speaker hasn't worked since. TBH there is no real need for it with the new setup. Since the C70 has no great pillar gauge pod options, I always thought it would be cool to replace the center speaker with a pod. So after a couple years of daydreaming about this, I finally dove in. I ordered a generic dual gauge pod from amazon, and then using a dremel, I flattened out the original mounting plate on the dash.. then a couple evenings of fiberglassing and smoothing/painting, I have a result that I'm happy with. This pod holds glowshift boost and Wideband A/F gauges as well as covers a passage for the radar detector wire to enter the dash.
The finish is black hammered spray paint covered by a matte clear coat. it's not perfect, but matches the dash pretty well.
