Hi,
Not sure what the rules are re links but I have a TransK9 box for sale on fleabay, item ID is 133914198390. If you copy and search on that it will come up.
I've had the box for a few years (Disco 3, then Disco 4 and Defender) but no longer have a vehicle it will fit in. TransK9 is good kit, no squeaks or rattles after many years of use. The box easily fits two labs in.
Thanks,
Paul
