WTB: Escort Speedo 6 Tooth Worm Gear

Hello Everyone, I've finally worked out why my gearstick wouldn't fit my gearbox but I'll cover that in another post. Now that problem has been resolved I'm wanting to rebuild my gearbox but firstly I'm in need of a 6 tooth speedo worm gear for a Escort 4 speed gearbox. Also after a 23 tooth speedo gear (same as type 9) if someone happens to have one. Any help appreciated, thanks.
