I wouldn't worry about that hole in the rear tunnel. Not sure what it is for (my car doesn't have it), but I thought you were describing a hole drilled down through the pan.

Not to terrify you too much, but here is a good thread on why the glass leaks are such a concern. Note the sound pad under the rear parcel shelf - you'll want to get that out and dried: http://forums.pelicanparts.com/porsc...ance-item.html

To take out the rear glass you probably should cut the old gasket with a sharp utility knife from the inside. Then push while someone is on the outside to catch it. Need to be careful with the defroster wiring, not sure where the connector is located.

Everyone seems to recommend only using Porsche seals. Uro's may be getting better, but I don't have any direct experience. Place the new seal around the glass, carefully remove the trim from the old seal and re-install on the new one. Thread a rope (about the thickness of a pencil) into the seal where it sits on the body. Lube up with dish soap, then place the glass in place. While someone pushes from the outside, slowly pull out the rope. It should expand the lip of the seal around the body flange.

That's it in a nutshell, but it can be tricky. Just be glad you don't have a Targa that needs a new rear seal. Here are a couple of threads that may be useful. I couldn't find any good ones on Rennlist:

Great thread on doing the front, some of these tips will probably help for the rear too: http://forums.pelicanparts.com/porsc...seal-body.html

Good luck!

Many or most are in SoCal. One is TRE, owned by Dave B. (you don't want to see me try to spell his last name). There are others too.

I helped a friend do the glass on his '71 but I don't recall now what brand seals used - it was years ago anyway, so things may have changed.

As per above posts, these seals are different from all new cars (new = last couple of decades), and can be DIYed but a modern shop (and his wage slave labor) may not know what to do on these.

You might pull the rear shelf upholstery out and see what things look like first, but you have the symptomatology of R. seal-itis.
