Parts Are Hard To Find...
Oh Idon't know about that.
Yes, while it is true parts can be difficult to find for Hoover twin tubs, they often can be had. Mind you it can mean dealing with persons in the UK/Europe or in the "land down under", but there you are.
There is also many persons do have a decent stash of parts, but given how hard such things are to come by, often they aren't on offer.
