I know its a long shot but:

Long story short I received a transmission with a damaged rear case. I am looking to see if anyone happens to have broken trans and would like to sell me their rear case. I have a 82/83 manual transmission. I'm not 100% sure if any 5 speed case would work but with enough pictures we can probably figure that out let me know what you have thanks.

Still looking 

Dang i have one from a 4 spd.

I have one.  Should work.  PM me and address and I'll see what shipping costs.

I'll put the pictures here.  More interesting.  It's from a mystery 5 speed that Itook a chance on.  Ended up using the case to build a 71C swap.  The insides had broken synchros and the adapter plate bearing was bad.  Looked like somebody got angry and tried to blow it up.  But the cases were in good shape.

That look like the late 5 Speed case to me

That was my conclusion too.  You can see the reverse lockout mechanism inside.
