Broken lsd

I have taken everything apart and verified that it’s the lsd and good ideas to get this on the road? Like just slap a regular transmission in it and call it a day?
 
I had this happen last year. I bought a used but good LSD and had it welded around the ring gear for reinforcement. You can also install a used transmission with an open diff. Just depends on how important it is to you.
 
Honestly not worth the fix price for the lsd so I just need a whole new transmission that’s open?
