Generic 3rd Party Combiner accessories, where to buy?

Those ones look like they are from the c+ customs upgrade kit which does come in red

@Darksaber, you are correct, that is the C+ custom add-ons for Victorion, the only good pictures I could find where of the prototype models before they cast them in red.

But since that set is discontinued, purchasing it is not possible.

Hence why I'm looking for alternative add-ons now.
