So, my driver door is rattling a bit, and it's kind of annoying. I replaced the speakers and discovered that the driver door panel had already been removed once, to fix the power mirror I think. They busted the door handle bolts, of course, and tore off the rubber vapor barrier. So, does anyone know where to buy a replacement vapor barrier, and any tips to quiet the door panel rattle? I've considered just drilling holes and screwing the panel down.

Thanks in advance.

I added a pic. The rubber piece hanging down is what I'm after.

 

I would suggest just using some of that acoustic mat stuff like dynomat. But, I'd buy the cheaper stuff

 

I'm sorry but in pic I can't tell for sure but if vape barrier isn't totally dead and you just need a way to attach it back in place, clean the dust off the door and barrier and use gorilla duct tape to rehang it.

most older vehicles the barrier was just a plastic sheet I've even seen paper barriers

As far as rattle goes if the plastic attachment clips are broke most part stores carry them, but if the attachment points are broke on the panel its self you will have to find a different panel in good shape or do the screw idea - been there done that

 

Looks like you just need some pins to hold that in place. as for rattling, dynomat or second skin, something along those lines. They can get expensive quickly.
I went the ghetto way when I had my jimmy to stop the rattling and got some of this, stuck it in place and removed the foil. It worked great. Its sturdy foam with 2 sided adhesive.

Thanks fellas. odat, that pic isn't of my blazer. That's just an example of the piece I'm trying to find.

rich, that duct insulation looks promising thanks for the idea.
