Lefty,
I can't tell where you are located while thumb-typing on the mobile device. If in the UK, try calling Andy at leighclassics.com. When I was there he showed me an amazing storeroom full of parts. I don't know for sure if he'll have it, but it would be useful to know if he does and for how much.
If you talk to Andy, be sure to tell him that Richard from Chicago sent you, because I get a free Rocket Gold Star for each customer I send his way.
Richard L.
