Looks to be a very nice example that.

Your on the right forums for advice and spares but ultimately ebay is the main place to pick up the hard to find parts.

I wouldn't change the interior too much - it looks good, particulary those door cards they look very good -unless your old man is dead set on a grey interior I suppose it's up to him.

Nice find anyway, best of luck with it.

(lots of smilies here at the request of my young-un lol)
