I have been maintaining it well and doing pretty much everything I can to it that does not require dismantling the exterior or exposing it to wet weather. I drive it at least once a week and fire it up several times a week to keep both me and it happy.
I recently replaced some rear spotlights with new LED models, and this week I removed the painted-over plexiglass back window which had begun to literally fall out. After stripping down the paint and rust areas around it and covering it with several coats of primer, a local glazing company installed new 3/8" laminated safety glass with a really nice double adhesive application (one below/one above the glass), then troweled and "pointed" the channel. It ended up being a really great job for exactly $100.
Here is the finished glass

Here is the previous painted over plexi (left) and the opening primed and ready for glazing

new LED spots on the back ($24 for the set off ebay, free shipping.)

LED lights on, they are about 1500lumens each. You can see the metal canopy and frame in some of the pics - I hate having to see her under that thing. Its like keeping your dog in a cheap plastic dog house with a wet blanket...just....cruel. She wants to be warm and dry.

Scratched some paint away on the old window and found this sticker (applied the wrong way so it read backwards from outside). After googling I learned that "GullsprangsKraft" was the name of the first Swedish Electric company (which would explain the orange paint layer under everything else), they apparently used these to do power line work. I have seen old photos of powerline wire spools rigged onto the back of a C303 with a gantry. It was cool to dig up some history on this, it was like vehicular archaeology.

Hope everyone is well and keeping it between the rocks!
