Nige, do you know how the drain pipes get from the sill to the front wheel arch? I mean I have seen them go down behind the box section is where the door hinges are but it goes into some metal and them vanishes.... I am going to have a look but I am conserned that a previous owner re-routed the pipes as he has fiddled before from what I can tell.
Sounds like you had a good day Peter, a job well done.
As far as I can remember the pipes just pop out into the rear of the Front Wing. Can't have a look for you as I fitted the Inner Liners from a 75 so no easy access into there. The end of them comes out of the Wings just behind the Wheel Arches. To get the new Tubes down use the old ones as a pull through using Masking Tape or similar to join them together, worked for me. Wish I'd taken more pics now as my memory is rubbish.
Yesterday I bit the bullet regarding the " A " Pillar Trim. Was in the front having a smoke and looking at the '6 when I decided I couldn't live with how the Trim was " fixed " on any longer. I pulled then both off, which wasn't difficult and then spent half an hour un glueing the fold over bit of vinyl. Then I poked through the holes in the " A " Pillar to see how far in the Drain Tubes were. The top hole had very little, if any, clearance between the Pillar and the Tube, the other two seemed to have a fair bit of clearance. Of course the most important screw is the top one, you have to fix the Trim at this point, didn't bother with the bottom one as this wedges into the Dash well enough. Used the shortest screws I could but it was hard to gauge how far into the Pillar they went, I'm hoping that no damage has been done......
Thinking about it though even if the screws have slightly punctured the Tubes my theory is that 1
. The screw itself will actually seal into the Tube and 2
. If the Tubes are not blocked then the water should naturally run downhill past any slight punctures and not sideways - time will tell......
Looked at the Tubes I took out yesterday, the original Alfa Screws went all the way through the Tube,
at least I haven't done that !!!
Looking forward to hearing of a successful conclusion from you soon.
