3 pt pc behind my seat

My newly acquired 3400 has a broken piece where the top stabilizer connects to the tractor. The bracket is still connected to the rear housing but it's broken loose from the shock absorber looking things. Is that piece replaceable or do I need to get it welded up? The broken piece on there now is just a thin looking threaded nipple someone welded on the end of the shock, or whatever it's called. I see it's bolted to the tractor with 3 bolts. Can I just unbolt it all and maybe get a harder more durable bushing welded on it?
