I think the 'manual' folding mirrors are all black plastic, not body coloured, and maybe a slightly different shape.
Try a scrap yard or auction site.
The door card comes off quite easily, 1 screw for door handle then 3 for the armrest, then plastic locks around the bottom and sides of the card. Be firm but gentle.
I think the mirror assembly is held on with 3 bolts, front one under a cap. The connectors look the same, but can't say for the wiring.
