I've not been able to find anything with that's to the Gen 2.5 honestly. If you or anyone else knows of the thread and can post it here- sounds like several of us could stand to benefit from this link.Yes there is a way to retrofit one, if you use advanced search with word "cabin" or "dust" i think you'll find the post about it. One of the southwest members on here cut a hole and added one to reduce all the dust getting in his mont out in the desert.
