If the E-type fellas can have this topic, and on other vehicle forums…
I used to try and average 1hr per day while I was working
after 20yrs ownership, I decided to finally sort out the locking issues in my 420G!
Promptly locked the boot and could not get it open, it popped open at 90mph!
Once home, I dismantled and lubed the entire mechanism, every piece…it works perfectly now
In addition, my single teardrop DS rear view mirror has erectile dysfunction since I owned it
The internal thread must be stripped in the “hold” position
I recently accquired 2 x used MKX teardrops, so that mine can have a matching pair
they have the wrong headed screw in them but it holds.
I suspect the threads are subtly different (original thread likely to be an odd BA or BSP thread imo)…off to the fastener specialist to get the right head, and a thread that will hold.
In the meantime, the mirror does not droop down useless on the flank, but stands proudly upright, doing its job
