Rear end mounting question

Yeeah, I just watched a video of why NOT to weld spider gears lol. I put an wanted ad up in classifieds for a rear that'll bolt on but I'll still stalk marketplace.
Thanks man.
If you can get it for say no more than 100 bucks. Jump on it. That'll make it worth it to fix it up with new carrier and such. If it's complete with brakes and all it's worth that, although barely.
