New rubber for the vent windows is available from IPD. Installation requires taking the glass and the strut at the rear of the vent window out of the door -- it's quite simple, but work slowly and analyze how it all goes together. You'll need to drill out the rivet that serves as a hinge for the vent window, and drill out the rivets that hold the rear of the old rubber to the strut. It's quite easy to pop-rivet eveything back together, so buy or borrow a pop-rivet gun.

On the roll-down window side of the strut, get some rubber window channel from a junk 140. It's a good replacement for the stuff that used to be in there. It just presses in. For the fuzzy stuff around the rest of the window, I used some generic channel from JC Whitney, which you cut to length as needed. I believe the "real" stuff is available from various Swedish sources -- see RoundFender.org for a listing of those sources.

Windlace is the cloth-covered, round-section strip that goes from the floor of the car up to the headliner and back to the floor on the other side of the door. It's NLA from Whitney, but is available from the above-mentioned Swedish sources. It's also pretty easy to sew your own.

Rubber door seals are currently available from IPD.

No suggestion on the intake roar... I like it.
