So I swapped the interior back... had to re-do the the headlining, which involved getting the back window out, so I replaced it with my old non-tinted window... was lucky not to destroy the old windscreen surround; it's a bitch of a job. Got the front screen out to find a mile of rust... fixing that took a while.
Had to swap the driver's door too, and found a bit of rust under the upper hinge...
Body's pretty much sorted; there was another rust repair I had to do under the window behind the passenger door... interior's just about together, just have to put in my good dash and the front seats after I get the windscreen installed.
Now, I'm onto the hard bit... gotta swap the engine. I don't suppose anyone around my neck of the woods can lend me an engine hoist...?
