HJ Holden demister duct removal and installation

[Indy Orange]

G,day all,i need help in removing and installing a demister duct ,the lugs on mine snapped ,I managed to find one with the lugs intact that I pulled from a wreck ,I unscrewed the wing nuts and two lower screws holding in , hoping it would come out from under the dash, not so, lucky it had a massive rusted hole in the floor that I passed it through to get it out.Question is ,is there an easy way to get these in without taking the whole dash out?there seems to be nothing regarding this in my workshop manual.Any advise greatly appreciated.Paul.Picture of the duct is attached.Example pic from ebay.

Shouldn't be too hard mate, I dont understand exactly what you mean about snapped lugs, or the hole in the floor (I take it that was in the donor vehicle).

But yeah you can get that in without removing the dash (easier with the glovebox out) - but its not the way to do it. Taking the dash out is usually quicker than the stuff around - its half disassembled once you've got the glovebox out anyway.

You obviously want the demister to work, so the ducts and plastic bits need to line up properly nice fits, no gaping leaks, nice and straight, and you may as well check all the cables are working properly once you finish the job (they're simple, but easy enough to dislodge or wedge/twist/jam if you cant see your final result), so, I'd just take the dash out, (have several marge containers or etc to put the different size screws in and know where they came from) and then you can set your demister system up properly, and be confident its correct.

Taking the dash out is less than an hour if you're organised, putting it back same time. You could easy spend heaps longer tryna manouver the duct in with only the glove box removed, and you may not get it in the right place, (and you get to clean your air system out at the same time. - it is bound to be pretty dusty).

everything bar the instrument cluster needs to come out to get that sucker in and out. should only take you 15 mins to get components out and another 5 mins to remove the y piece in the image. the wingnuts get rusted on an its a bit of a contortion job but easy enough. Very common for the tabs to snap. Pass it out on the passenger side to avoid the pedals from memory.

Thanks so much for the replies Dave and Vombil,I think I'll take the glovebox compartment out first and pass it out from the passenger side and see how I go ,I also have a front speaker I want to mount where the wing nuts are(saves cutting holes in the kick panels).thanks again.

Cool! I'm interested in these, seen em before on ebay (US) and they have come up before about half a year back.

I'm interested to know what they can sound like. Bearing they are replacing an old Rola-Plessy, and that mostly people would just connect the old radio up, is not a test, but that baffle looks good to me, I wonder has anyone got one of these running with decent headset?

How are you hooking yours up Indy?

Looking at the design of these, I think there is a chance they might sound Ok, I'm curious bout these. In a previous thread, the last comment said something like 'no speaker can sound good without a decent sound box'... well actually thats both true and untrue.

All loudspeakers of course used to need a decent baffle, in the 80's and 90's this was usually handled by the enclosure (or sound box) but modern tech on loudspeaker design has produced some pretty awesome sounding devices without this. (Not Hi Fi, but closer than one would have imagined) I have wondered, if the idea with these is that the mount to the metal behind the dashboard could create a soundboard.

Anyways, great choice, how does it sound?
