Also not worth LS'ing it, as then it gets a performance mod plate and no good for NSW P platers....
As you say, it's an early one with the split rear window - there's a couple of guys who have similar vintage ones, and are doing them up slowly, so keep an eye on their projects for where they source parts.
It also looks like a single rear wall, but I'm not sure if that's a split rear window norm.
Does not surprise me that you now have mates sending you 40s from everywhere... if you find any under $3k that are presentable projects, grab them!
Oh, and you don't need to move the Dunnydores, you just need more sheds
