Yes you take of the gloss black inner handle, and whole door card. its not complicated.
Then you need to drill out the snapped hole. I used a 4mm then 8 or 12mm larger bit at end .
Then grab a bolt with large washer at the head end (this basically spreads the weight across the rest of th plastic handle bit) I think the washer was about 30-40mm but just see what fits in the handle section.
Then in the rear of the door card I used a loctite nut, again quite wide outer diameter - maybe 20-25mm (or could use a washer)
The idea is basically it puts the door weight spread across the washer/nut and the bolt just holds it.
I went crazy with 1 x larger bolt and 1 smaller at top as a precaution
Door is now bullet proof and far stronger than a new 1800 $ door card
