If you go to Vintage Scuba - Vintage Scuba Gear at Vintage Double Hose
At the top there is a link to Manuals & Catalogs.
After you click there, then click continue.
You will then find a list with many manuals and catalogs.
What you need is under Scubapro schematics and parts list
You will find the vintage Scubapro schematics marked up with generic O-rings.
Have fun.
Good site! Here is another one you can try.
