So I have rebuilt my 69 astrovents and lets just say the are repro parts and may be lacking in some areas
(I am not sure R or L, but they only fit one way)
Clockwise from top left (inside of astrovents clamped by metal, pass side duct connector, firewall to duct seal, other side firewall to duct seal, pass side vent assembly to dash isolator, drivers side vent isolators (two strips), and screws)
So I tried to find my spare set this morning and could not find them, so this is from memory, which at my age might not be all there
The flexible ABS ducts mount to the firewall with those special 3 large headed screws, the circle seals get contact cemented to the ducts, but not to the firewall. Screw pressure seals them.
The pass side has that intermediate dryer vent hose that connects the ABS duct to the hard plastic vent assemblies.
Inside the ABS duct is the flappers. The flat sheet rubber is for the flappers. The flappers are mounted on shafts, remove the flappers from the shafts, pull out shafts, then you can pull up flappers. The rubber sheet is sandwiched between two metal plates riveted together. Grind the rivets to separate. Pop rivets work well to re-assemble. Note, sometime the ABS is cracked around screws and shaft holes. You can use ABS repair kits and a soldering iron to repair.
So the large foam and the two strips are the weird ones. On the drivers side the hard plastic vent assembly is mounted in the dash. The two strips (top and bottom) are used as anti rattle isolators. Again contact cement them to vent assembly, but not to other side. only one side gets glued
The large rectangle must be for the pass side isolator. I have a early 69 and seem to recall the same two small strips on the pass side same as the drivers side. But pay attention to the seals and isolators that are there and duplicate them.
Also now is the time to replace the chromed dash vents and felts!
