Vintage parts

[JOHECEAR]

Hi, I'm a proud owner of a black dial 1500 and of a 1510-8. Since you’re all experts on vintage ones like mine, perhaps you could help me with the following: 1. Where can I find a pre-owned, replacement black (or white) dial for my 1500 (because mine's is stained)? 2. Can the milled bezel of the 1501 can fit the 1500? 3. Where I can find a pre-owned, original Rolex (or Cellini) brown leather band for my 1510-8 (because mine's is missing it's factory gold bracelet). By the way, I’m interested on a pre-owned, classic Stainless Steel, Datejust, with a Jubilee bracelet with a black (or white) dial. Is there any source you could recommend for that as well? Thank you!
