W114 250CE 1971 bulkhead/heater plenum leaks

Hello ! Some advice please. I have a 1971 250CE coupe currently being "refurbished" for the summer. I am nearly there but have one or two annoying jobs to tackle.
The main problem is rain water leaking from the heater plenum chamber in front of the windscreen down into the front footwells. I have had a good look into the box section having removed the wipers and the ally grill. The box has been repaired in the past and plated on the bulkhead. I cannot find the drain holes from the box section - where are they located and where do they exit below the car ? Are they pressed channels in the car pannels or rubber pipes ? Any guidance gratefully received ! There was alot of debrit in the bottom of the box which I removed but I could not find any drainage exit holes. Thanks Iain
