A little cleaning up required and a dab of paint too.
What is odd about this is that my first Beta, a 1978 HPE had the early brown dash and mustard trim with the earlier triangular tipped stalks. When the interior wore out I bought an entire interior from a later car including the dash and everything swapped over without any (major) issues. I also have a memory (which may be faulty) that I converted the stalks to the later ones, also from a LHD car, but that that was a straight swap. I'm probably imagining it.....
