Kinda a parts question maybe you can help 71 blazer (Back Latch Question)

[BlazerBoy]

I have a 71 blazer and i am fixing it up and well everything's fine cept the back hatch door locking mechanism. the handle broke off so i took it off and it broke the spring loaded latch on the inside of the hatch door so i removed that as well and its all rusted to hell and now i am just wondering how i would go about getting that ? and what is it called ? is there a part # ? any and all help would be nice
The reason i did not post this in the parts section was i guess i am too new or something and cant post in there ? So sorry to whoever this pisses off that it was placed in the wrong area.
