Vintage Ed White 105.003 - Need Help Sourcing Parts

Hello all. I am new to Omega Forums. I recently acquired a vintage Ed White 1967 104.003 Calibre 321 Speedmaster and it has a bunch of service parts such as the:
1 Tachymetre bezel need dot over 90
2 dial
3 hands.

Everyone I asked said that this watch shows common Omega sanctioned service from 10-20 years ago. I would like to restore it to its pre-service glory with original parts for a fun project. I am writing because I would like to know if anyone has any connections to where I could source said parts. Sound off below if you can help out in any way.

Thanks in advance for your time.

Everything you want to buy, you find on eBay. Ball park figure would be US $ 5000. Good luck !
