Both front seats available: Original basketweave vinyl type. I’m sure there’s a more technical name for them, but there you go. There’s no runners but they should bolt on nae bother. £30 the pair.
I’ve also got a pair of original bunk beds, with somewhat holey black and white checked fabric. I don’t think there’s any fittings to go with them though. A tenner the pair.
I’m in East Lothian, so PM me if you’re interested. Don’t be shocked if I don’t get back to you immediately - I’m wicked slow at this stuff.
