1/8" thick by 2" wide or so strip of steel from any home/hardware store.
Remove the handle pin that the handle pivots on. I had to slightly grind down a peened over section to be able to pull it out. I used a dremel with a high speed cutter bit to get in there.
Long and skinny needle nose pliers and a pair of linesman pliers helped here.
Trace hook end onto steel. Making sure to also scribe hole for the trip rod.
Cut out the outline.
And drill out the hole for the trip rod. 11/32" I believe.
Cut off old plastic hook. I just hacked it off with a 1/8" cutoff wheel on my grinder. Precision wasn't a big deal.
You have to cut into the blocked off end of the handle so you can insert the new steel hook.
I decided to also have the pivot rod run through the new steel insert. Just trace the hole using the pick or an owl.
Then I installed the new insert, lined up the holes using the pivot rod to keep it in alignment, and drilled 2 more holes so I can put in some reinforcement pins.
I used a couple small nails I had laying around, and drilled the holes to fit. Then I used some plastic epoxy inside the handle and on the new insert for extra help.
Put it all back together, cut off all but 1/8" or so of the nails. Put the handle in a vice and crimped the nails down to hold everything in place. Make sure you only catch the nails..
Reassemble the handle, reinstall in to the door with new rivets..
And you should never have to deal with this $!##$^%@# door handle breaking again! (this was #2 for me!)
BTW, this little tool here has become invaluable for working inside these doors and quite a bit else on these cars.
Took about 45 minutes to do. I've gotten good at working inside the doors..
