[Closed] Show me your bike van securing methods (please!)

Just bought a LWB Transit Connect for bike transportation duties. Looking to secure 2 bikes, my commuter and my play bike. I live 25 miles from work so I drive in so far and bike the rest. Having both bikes in the back also means that if I go for a ride after work the play bike is to hand.

So, just looking for quick and ingenious ideas as to how to secure them

The load space isn't quite long enough so I'm already considering cutting a slot in the bulkhead to slip a wheel into. I know about floor mounted fork securing brackets but I'd prefer to leave the wheels on. I'm reasonbly handy and have access to fabrication equipment
