So I got my replacement door handle. Cost me 16 bucks delivered to my doorstep while I was in CA.
I examined and compared the new door handle to the old one and while some details are slightly different, I could not see any downsides in design or "quality". Let´s see how the new door handle holds up.
The removal and installation are well pictured in several YT videos, so I will skip this.
The rear insert in my drv side front door handle was spinning freely, so unbolting it was not possible. I slit out the handle with a little force and might have broken the plastic part the insert sits in, I found bits and pieces on the floor of my garage. I swaped the lock and locking rod from the old to the new door handle, greased the new door handle, put it back in place and was done with it. Door opens and closes, locks and unlocks as it should. Fitment is good, although I believe the new gasket in some places is a fraction of the fraction of an inch off from the sheet metal.
I ended up using JB Weld to glue the OEM insert back in the old door handle, trying to use the broken off pieces and glue them back in place, too. Of course some gaps occurred as I was missing pieces. After the JB Weld had cured I used some Presto Adhesive Steel to reinforce the repaired area. Presto is a reknown brand here and I have used this product ever since I started working on cars some odd 35 years ago. The product is a 2k composite and behaves similar to bondo. After curing is gets very hard and can be drilled into, tapped into, sanded, painted, etc. My experience with it is good.
The repaired door handle is on the shelf now in case the new one breaks again. Oh, and I try to use the door handle diffently now: Instead of pulling the moveable part with the full hand I now try to remember to use the thumb against the lock and sort of pry it open.
Here´s some pics:
