Is there meant to be plastic tacked in to the inside of the doors between the back of the trim and door like in modern cars? My lc has nothing but that doesn’t mean it’s meant to be there

There was a membrane glued to the doors in production. Kind of a plastic coated material, Typically a light grey colour but other members have reported other colours also used. 

Easily torn when being removed.

It's there to stop drafts and moisture coming in around the door trim / inside handle / window winder

 

If you've ever had to drive a couple of hours in an old beater with a busted heater in the wee small hours of a freezing cold morning then you will appreciate those little pieces of plastic!

It also stops the dust circling & go into the linkages, is what i was told as an apprentice, my boss was a gmh panel beater just before lc. We were always instructed not to tear them, or if they were missing, to make up new 1's we used to get a thick clear plastic stuff, i seriously can't remember where from though nowadays. So yes, put them on, Gary.

Thanks gents

It's like a light canvas ,plastic coated on one side.

On more modern cars, a missing piece allows water to get into the car through the door trims.

My VT was filling up the foot well until I reapaired the plastic.

The top of the window frame relative to the bottom of the door shows the problem.

 

On a side note, would love to know what type of adhesive is used to keep them in place.

Non hardening and reasonably reusable

I just used this stuff on my ute doors and some Selleys butyl mastic.  Would have been a bit easier to install if the plastic was a bit more workable and I was more careful/patient about it.  Will probably use in on the Torana unless I see/hear of something better in the meantime.  Cheers Ron

I replaced all of mine on my first torana years ago, just used black poly from Bunnings garden section and non hardening mastic, seemed to work well.

If you want to go the more expensive route I was just at Car Builders and they now sell the liners in a kit.  Comes with a "tape" which looks like licorice and feels like firm mastic.  You run this around where it needs to go and if you want to remove it later, I'm told you simply slice through it long ways (if that makes sense) and it will re-stick to itself when re-attaching. Cheers Ron

Sounds like a possible issue around your mirror seal, if you're leaking into the door, unless the belt strips are stuffed. They glue back together with loctite 406 if the rubber is separating.

The stuff to use is called Butyl or Butyl Mastic.  Bunnings have it.

The belt strips arent a real close fit to the window, but they do touch.

There was enough seepage past it to allow water to enter.

The angle and shape of the door meant that the water was hitting the inside shell of the door and running through where the plastic should have been, down the door card then into the footwell. Was mainly during really heavy rain that it happened.

Light rain didnt seem to do it.

Took a while to chase it down, but as soon as I removed the door trim I found the problem.

It had had a window broken and replaced, and the lazy person that fitted it didnt bother neatly removing and reinstalling the plastic.

Once I repaired the plastic there was no further problem.
