you can see rite through the  duct
    a guess from me is that there should or could be a butterfly  to open or close the duct.

Looks like the duct has come apart. Can you push the two together?

I checked the duct and it definitely looks like its come apart. Tried to compress it together but could only get about 5mm out of it. Are they easy to remove and repair because there aint much room under there?

Checked the firewall while I was under there and there were no holes in the firewall, looks like all rubber grommets are still in place.

The duct definitely comes apart and yours is just about there.  The scalloping or 'hole' you see should be pushed inside, mine had done the same and it was previously PVC duct taped - don't waste your time as the tape quickly gets hot and hard and you'll be trying to clean it off next! It looks like GM use double sided tape - if you can slide it together, you may be able to do the same, or else use an adhesive that cures so it will hold, but can be removed by a sharp blade down the joint without damaging the plastic at a later date.  Sikaflex type, but it could stink a little as it cures and heats so there may be better water based products.

The heat restricting flap is mounted inside the duct above the one you show in the pic.  it has a control cable connected to it, pretty sure the ducts pictured are just to direct air downstream of the flap.   

My ducts are out of the car, they were easily removed, but I stripped the whole interior inc dash so not sure what contortions you might need to limber up for...  If you want I can take some pics of duct pieces on the w/e so you can see the metal tabs that screw up, but I find sites like Corvette America etc. have pretty good assembly manual diagrams and most often photos of the parts - just search the part description.

Like the other guys, I have spent a lot of time putting good quality sound / heat insulation under the carpet, under the trans tunnel and there are also foam seals between the chasis and body at the firewall and between the tunnel & trans (mines auto & I am not sure if this is factory)  - but i didn't do external to the fire wall, good idea!  But with the block hugging extractors and side pipes the exhaust gets out just behind the wheels so I'll get a sore ear instead of hot legs.

Good to see the PCV was a common part, great looking car and have fun with it!
It was supposed to be 12 months and a tight budget.....just a few simple repairs and a coat of paint.....

Guess I've got 2 options to fix the duct. I can either find 2 grommets for the scalloped holes and just plug them up, or find a way to squeeze the duct together and fix it properly with double sided tape. I might try and squeeze the duct together with a G clamp but have to be mindful I dont squeeze it too much and crack it. I'll give it a go over the weekend.

Can anyone give me some advice on the reproductions seat covers from Ecklers, Corvette America and Mid America Motorworks? Whats their quality like and why Ecklers lists only Medium Blue for a 72 and Corvette America list only Royal Blue for a 72? Just trying to nut out exactly what reproduction seat covers I need to buy.

Thanks all.  :bouncesmile:

Have a look at Wilcox for seat they are very good and will give you the advise you need.
1972 was royal blue by the way not medium blue but they will give you a sample color via the net if you ask.

Thanks Rosco. I sent through an email.

I need to replace the clock but then everybody probably already knew that. Think I know where to get a 2nd hand one. Are they easy to remove and replace and what needs to be removed to change it?

The hole is normal part of the duct tube that goes to the drivers side ball vent in lower dash.

You can see the remnants from the stick on seal tape that goes around that duct where it pushes together that is meant to seal it together where it joins.

It is not pushed in fully, that's why it's showing up like that.....however after 40+ years the parts don't always go together as well as they should.  (To be honest they probably did not go together perfectly when new :)

The tube is held in place at both ends by pressure and there is a bracket with a screw that mounts near the bottom edge of drivers dash, next to under dash light and odometer reset knob.

Remove the screw and you can move the duct around a bit more.  then bend bracket to fit again once happy with position.

See if that helps.

Cheers Craig.

I tried to super glue it together yesterday while holding it together by hand but the glue just wouldn't hold. I'll be going down the street tomorrow so I'll try and get some double sided tape and seal it up that way.

In regards to the seats. I sent an email to Willcox Corvette and all they can send is a picture of what the seats look like, not really too helpful in my opinion as the colour might still not match the interior. I'm hoping their supplier might be able to send me a sample through the mail but thats probably a long shot.

Got a problem with the alarm too, not working at all. Do these alarms have a fuse somewhere?

Thanks all for your help so far. More questions will come no doubt.

Cheers.

clean the duct  in the area  to be joined  with acetone. its very potent crap so lots of ventilation when your using it .
use plumbers silastic ( as it is air harding )
sikaflex   make some good products as well,

you will need to keep the joint together over night to make sure it will stay there.

I would not try and glue or silicone the duct parts together, feel free to put some tape over the hole but consider ...... You may have to remove the cross over tube at another time when you want to get to wiring, drop the steering column, update the duct balls etc etc.

As for your seats my 71 is Bridgehampton Blue and I purchased new seat covers and foams from Wilcox corvette (made by Corvette America) Perfect match and I think it was royal blue, check my build thread for details.

Check this site

http://corvettec3.ca/interior.htm

Looks like the blue code is the same for 71 and 72 even though in 71 it's called dark blue.

Do you have any pictures of the current blue seats.
