mate in the exact same position. my advice, cool your heels. youll find a shell

I have an HX that dosnt NEED a shell but its windowed which i dont like. It took me 6 months but i located a licensed driving windowless HZ 253 trimatic for 2 large ones. Its not rust free but its miles better than the HX.

the roof looks pretty knackered on yours. Id definately wait it out and start with a better product. No point in tipping big biccies into a bucket of rust
