I had these crates made for the back of the Yukon, the smaller one is big enough for Cujo, so will definately be big enough for Lyka since I highly doubt she'll be bigger than him lol. They're not 100% how I would have liked them, I need to find a local aluminum shop to cut some holes and add some more bars... I wanna be able to see thru the crates so I can see behind me, the way the bars in the doors are placed, I can't see straight thru! I also need to sand them down with fine sandpaper and polish em, they are totally unfinished, not even brushed, so they metal surface looks kinda ugly with manufacturing scratches and such. No biggie, I've done enough aluminum polishing in my life to not worry about that lol.
