Transit connect interior mirror

[Basherdrummer]

Hi peeps, we have just acquired a 2016 Transit Connect to cage out and transport our agility dogs.
We’ve cut an aperture in the bulkhead but want to fit an interior mirror to keep an eye on them during transit.
It has a black plastic housing on the windscreen so can someone advise me what mirror I need to get in order to attach to that please?
TIA.
