The replacement radio has arrived and certainly looks very nice, to my untrained eye anyway. I emailed Konigs about the bezel and they swapped it for the beveled type, so hopefully I now have what the well heeled music lover could have picked when the car was new...
I haven't hooked it up to power to see that it actually works,Im assuming it does but I may hook it up and bench test it in the near future. The finish is exactly what I would hope for, the bezel and knobs etc are repro for sure but Im ok with that. I think it will look a million bucks in the dash when the car is all finished, although still a long way away.
My next question is how do I mount the amp? I had a look in the tech manual and the mount instructions are in there in German. Im assuming it uses the square hole in the middle of the firewall in the picture, with a captive cage nut like the steering column has. I don't suppose anyone has a copy of those instructions in English??
I guess I also need to find all the clips etc for cabling. I had the little auxiliary fusebox in my car but it was mounted near the brake booster, not near the voltage regulator.
Thanks again to everyone for their guidance with this, I would have been mighty upset if the other radio had been installed then to find out it was incorrect.
