I'm restoring my 71 250CE.

When i took the headliner out i noticed the drain hose from the sunroof was dry and cracked.....of course i tried to fiddle with it and now it has broken off at the slightly rusted metal outlet part of the sunroof. - it seems stuck in the cavity for it.....

How do i pull the whole thing out and replace?

where do these hose lenghts go - i noticed the rear ones are only a few inches long....

on your car they should drain out just about the rear wheels, but they need to go through the trunk first.
