Black & Decker Workmate (Duddingston EH15)

This needs repair. It was given to me, but I don't need it and can't be bothered with the repair. The thread has stripped in white plastic parts (see second photo), so they'll need replaced. They are eaaily available (I can supply a link) and it would be a fairly simple job to fit them. It was also left out in the rain for one night, so the tops are not perfect. To discourage the click-now- think-later merchants, please let me know in your reply that you understand it needs to be fixed.
