Rear Fork? (
I hit a rock and my rear derailleur was ripped off the fork. The thread was completely destroyed. Unfortunately my bike is kind of old, and that particular part was not yet made changeable, so I have to replace the fork... Which is going to be darn hard to find.
that is how the fork looks like (picture before the accident)

I tried to look up a fork and its components but no luck at all.
I had an idea of making a Way around, by making a metal part, but its going to take hours of work.
What you guys think can help me out?

1) Maybe a heli-coil insert if the dropout is not too bent ?
2) Can you use a derailleur with a built in hanger that clamps under the quick release ? (better than nothing)

If it's the derailleur hanger (the part the deraileur attaches to) as may be the case since you've indicated thread is stripped, you can get seperate replacement deraileur hangers: https://www.sheldonbrown.com/harris/hangers/
Also, the axle mount claw deraileurs may be used as an alternative.
If the dropout (the part the axle slides in) you probably should see if a shop can fix the dropout-replacement dropouts exist but generally require welding back into the swing arm.

There's a reasonably priced gizmo called a "drop out saver". I'm thinking your LBS should have one. It looks like a T-nut with a thin hex flange. Stuff it into your stripped out dropout from the inside and the derailleur will bolt right up.
If you had a biff hard enough to strip out your derailleur hanger, there's a good chance your hanger needs to be realigned.

take it to a shop and let them put a DAG tool on it

The back upper tubes are called seat stays and the lower ones are called chain stays.
