Class work as always Joe, great to see how it's coming along (and pleased you've added it here as I'm trying to stay off Facebook 😁).
The fuel tank and filler came up really well - that's cool not having to replace them (though I don't think the filler is available so nice one for protecting it).
Rover parts/fittings come to the rescue quite often now, and like you say are so much cheaper than honda would have been if they were available.
