Hi Paul,
Welcome to the forums
I actually like the mid 70's interiors...but they aren't for everybody. Maybe the best thing todo is either A) fix up the unit you have for resale, the short units are very popular B) Sell it as is get your money back and look for the unit you really want.
Run a board search for Tambour and you will find all the info you need to find repair parts.
Good Luck and let's see pictures we love pictures around here
