Door Striker, Door Jamb Area Metal Fatigue Repair

While In the process of repairing, replacing worn out door moving parts on my 39 year old Chevy; and as part of the process I wanted to replace the beat up door strikers...

I Pulled the first one off on the passenger side and found metal fatigue cracks, from door slamming and wire brushed up to see how bad & to take a picture (attached).

As you can see from picture I caught it early enough where drilling a hole at each end of crack, v-ing out the cracks and a little mig welding and grinding would probably be a good fix for many...

I'm thinking it's going to do it again next to the welds IF I don't weld something up behind it too...

Therein lies the problem, I don't see a way around cutting a big ass hole from inside the cab to do it and then weld that back up :-(

Has anybody done this kind of repair on a square body door jamb before?

Was your approach any different and how did it hold up?

thanks in advance.

Video a member here made and posted to Youtube. Super comprehensive on the subject.
 
I've got the same thing happening on my '77 driver's side. Just need to find a way to weld it in. Looking at a new door from LMC, hard to find anything used for these K5s anymore...
