This is what my interior looked when I got it (after a few hours of cleaning mind you). Missing bits, switches and a mess of wires.
Added a Triumph Spitfire headlight switch, some scrap sheet metal and a little paint I added the panel around the heater controls. And that panel below the heater controls? I created that with some misc early Niva interior plastic, some wood wall paneling, and some random switches (one from a 70s Mini and other two are just old parts store ones I had in my stash). The wood grain give it a bit of class eh? 🙂 No out of pocket expenses so far on the interior. I know its not perfect but its functional now! Floor mats added from the 1991 Niva as well. Just a few wires to re-hook up now.
