This forum is (in my opinion) one of the best out there when it comes to active users as well as the quality of information on the site. It would be nice to bring that to some of the newer stuff.

If it's easy enough to set up, then I'd say the three generations in their own sections would make searching/finding easier. There could be a rolling Q&A thread for people to use then copy paste into the relevant pages if desired.

I recently decided to do this Job myself.. until i stumbled upon a retrimmed headliner at the wreckers, so just bought it and swapped it.   I first removed My old one, because My plan was to drive to the wreckers without it and fit it in the carpark (would barely fit in the car any other way)   using the videos below as how to's, i managed to remove the old one fairly confidently, and then at the wreckers i got the reconditioned one out in less than 20mins.(didn't time it, but didn't break anything, and used a screwdriver to lever out the plastic plugs, no fancy trim tool)

I haven't got to fully refitting the new one in, been focussing on other jobs, but it's in and holding itself up. 

in My wagon, the headlner had a sunglasses holder(broken) and the new one didn't have the map lights or sunglasses holder.. and i decided not to mess with it.
the BA style sunglases holder is double the price of an AU one on ebay ($200 Vs $100 ish) so be careful if messing with either, as the BA style one that was in my series 3 AU crumbled on removal. 


 
   

Welcome to 2025 with a good suggestion Dean.   We have sections for F-Trucks, Cortina and Escort so I think it is a good idea to expand into the E- Series and AU.   The three Falcons my father drove in his lifetime were XD, EA and AU so I have a bias towards those three generations which aren’t always well received. It does hurt every time I see an AU getting tuned into a budget skidder.

post your suggestion below, and I'll find some time to add them into the forum.    there will be a detailed and specific AU section for sure, as i am a new owner and would like to see info easy to find for Myself any anyone else lucky enough to find themselves a non skidder classic to own and enjoy. 
so should we have an EA to ED,  EF and EL and AU, BA BF and FG section added? 
is there any structure you'd like to see or just a facebook style rolling Q&A style for the moment (much easier initially for Me/admin to establish)    Thanks for your time and input, 
Dean.
 

This is a trial thread, as many X series owners also have modern fords. and info is starting to be harder to come across.    What i'd like to do here, is begin a useful reference to certain common issues with links to other forum topics or Facebook groups or YouTube etc.    As a new owner of an AU, i found it quite difficult to find easy to follow steps on things without a lot of time googling and searching.    such as, how to remove a headliner so it can be either dropped off at a trimmer, replaced with a second hand one or retrimmed yourself.    this post is locked, and i'll start a suggestion box thread next.

I've had that sandwich plate rubbing before on a clevo/C4 combo. definitely worth checking. 
I'd also tip water over the fan/alternator belts, as silly as it sounds i've had them causing noises that sound nothing like you think

May be contact with a buckled sandwich plate. Don't assume it's the correct flex plate, make sure.   Yes, undo the nuts and see if you have some movement in the convertor on the studs. Should have 2 - 4 mm movement, at least. More could be an incorrect flex plate (unlikely, but possible).

Flex plate is new and I'm assuming it's the correct one for the C4.... Pioneer FRA-205.   Is it possible to check that without pulling the transmission off like undoing the convertor nuts and see if there's some movement?

Just listened to the video. I'm gonna say, that is the flex plate rubbing on the sandwich plate. Either the plate has a dent or buckle in it, causing it to rub on the flex plate and/or convertor nuts/studs, or the convertor is not fully seated and is forcing the flex plate forward to touch the sandwich plate. If you had this same noise before, something isn't sitting right there. The other cause could be using an aftermarket manual starter, which has a shorter snout, it could be interfering on the flex plate teeth. The factory used a spacer under the standard factory starter because the flywheel ring gear sits closer to the block rear face than the flex plate does. The whine I had in my C4 was MUCH quieter and more high pitched.
