Has anyone tried the Borgeson PS Box??

I have alot of play at the gear box input shaft. I can rock it back and forth. When I do rock it the shaft moves in & out. It's a rebuild from Rockauto.com, I look like a drunk driver when doing 50 mph +. I am also thinking about getting a Borgeson or Firm feel.
I sell my Borgeson bolt in kits. I’ve done so for 6 years now with excellent success. It’s the most costly of your options, but it’s the best, by far. Precise modern steering with a slightly faster ratio and a 15 lb weight savings.
