Rigged belt tensioner
The way it is now, you have to remove the bolt from the rod end to adjust it, which means you will have be be using a pry bar to tighten the belt while the other hand installs the bolt and tightens it down. The other complication is the limited range of motion. Most old school alternator brackets had about 2" of adjustment travel, which ends up being about 1" of pulley movement due to the pivot design. Your setup is probably about 1/4" before you run out of available threads.
If you use a RH & LH rod ends with an center adjuster sleeve or shaft, then you could adjust w/o moving the bolt and get more range of motion.
I guess the big question is why can't you use the stock tensioner setup?
