just carpeted the floor of my 74 kombi, and I noticed a whopping great hole in the middle of the floor (where the middle seat should be.) Looks factory made. Bit like a spout protruding forwards and down towards the front of the car. What is this hole for?

heating I think. Look underneath, should be a hose going to it.

no hose there. I can see the road thru it though, so I am taping it up.
Cheers, ian

your 74 kombi started life as a microbus.the hole you have found is for the heating of middle seat passengers. there should be a little hinged flap over the vent hole that is forced open by the airflow when heating is on
