Time to update this thread so it can be closed.
This project sat for a while, because I could not find replacement cups for the steering ball joints.
Tried modelling end 3D printing them, but the printer I had was not precise enough.
2024, I bought a new 3D printer, which was a lot better. So continued with this project.
The new 3D printed cups use regular C clips. Easy and readily available.
Got my hands on new drive shafts, flange nuts.
Glued the front tires and added MCI stickers.
Tried to polish the worst scratches from the roof. I later sanded the whole roof and re-polished.
Really coming together at last after painting the body and wing.
And finished after 7 years.
