Where can I get parts decently priced?

I've got an iPhone 8 Plus in Red, it's got everything but the screen and battery. The housing is bent and the back is smashed so that needs replacing. I've managed to find all parts I need, except for the camera lens cover, I can find them just not in red! I did find one listing on eBay that has the lens already attached to the glass back, but they won't ship outside of USA which is a problem as i live in NZ..

So is there anywhere else I can get a glass back with lens cover on it, or just the red lens cover? I want to stick with the red just in case i decide to sell it in the future, although I'm planning on using it as my work phone. Or is it possible to just replace the glass lens bit, and i reuse the red frame from this one?

I have mostly been looking on eBay, Aliexpress and TradeMe (nz only equivalent of ebay), but can't find exactly what I'm after.

Any help is greatly appreciated.
