Fuel Tanks

[degz]

My Tasmin has only got one tank (sing along if you like)for some reason my mk1 has no near side tank, there is no repair job on the one thats left to indicate that the other was removed, so I must accept the car was made that way.
Does any one know of a scrap car or set of tanks I can get, just fed up with filling up every 100 miles or so.
