Shark Fin Antenna Cover

[Corncrake]

I've either lost my shark fin antenna cover or it's been stolen. I've twice ordered a replacement online which was advertised as fitting my 2019 Outlander. However, both were too short (16-17cm) and would not fit. The length of the shark fin antenna cover needs to be about 23cm to fit. Any ideas as to where I can source this (UK)?

Finally managed to obtain the correct shark fin antenna cover. I had to go direct to Mitsubishi and pay £140 [!] for a relatively simple plastic moulding. That might explain why my last one mysteriously disappeared.

What holds it on, snap fit? Would a car wash knock it

Glue! Hopefully good enough to survice car wash!
