two cubs fit short side to short side across the load space of a Defender, two cubs stacked are 3" under the capping (rear firewall in a 90 or 3-door) 6 cubs cover the floor space of a 90 and 8 cubs cover the floor space of a 110.
Two wolf boxes fit long side to long side across the load space of a Defender, two wolf boxes stocked are the same height as the capping (standard lids) or same height as the window bottom with tall lids. 4 wolf boxes fill the floor of a 90 or 110, but the 110 will have enough leftover space for two jerry cans and 4" long the sides.
FWIW the wolf/cub boxes are not FrontRunner designs, they are new production of ZA ammo containers - and as such the corners are sacrificial to prevent fall impact from setting off ordinance. I've run a set of 6 and refrigerator as my primary setup for 8 years at this point and other than a couple broken latches they've held up to everything i've thrown at or in them.
All in stock all the time if you want them shipped or to come up for a visit - we get to open this weekend at last!
