I'd probably try Restoration Specialties: Welcome to Restoration Specialties - A first class restoration depends on quality products. If you send them a photo of the parts, they'll tell you if they have them, or something close that'll work.
If all else fails, I'd probably just use an appropriately sized nylon flange bushing and e-clip or retaining clip.
