Bumper indicators

[BMG]

One of my M3 indicators is missing the reflector part behind the lens. These are not sold and a complete indicator is NLA.

I know some E30's use indicators that look similar, but the bulb is more offset to one side, so are there any models which may have the same reflector ?

This is the M3 part

This is what seems to be all other E30's ?
