Van spare tyre

Does anyone know whether panel vans came with a spare tyre, and if so, where it was mounted?  I gather the Sundowner's had a bracket in the back, but what about the run of the mill work-horses?  And what is the little hook in the floor behind the drivers seat for?
 
Thanks.

I can't get even a skinny 155 tyre under there - it's just too large in diameter.  How did you manage it?

The spare tyre definitely does go behind the passengers seat in the cavity underneath the cargo floor.
When I first bought my Escort panel van in the early '80's the spare would just be able to be prised out with the seat pushed all the way forward and tilted as far forward as possible. The newer standard 13" replacement tyres are wider. So now to remove the spare the entire seat needs to be removed.

I don't know where I'm going wrong. With the seat moved completely forward and folded forward until it hits the dash the wheel still doesn't fit behind. Their original Escort seats as well. 

I have my one in at the moment
