These are NOT suitable for a stock TJ bumper; they might be suitable for a YJ/CJ bumper, being that those bumpers are made of MUCH stouter steel, IF the d-ring mounts are placed in front of the frame horns, but even then I'd prefer a Dixon-Bate Tow Jaw (pic from expeditionexchange's site)
Truly, though, I find the regular tow hook with the springy keeper thing to work just fine. You can slip a shackle over it, you can attach a strap directly to it, and they're cheap. Throw on some Grade 8 hardware and you're golden.
As for the hoop, both Ramsey and Warn offer hoops that bolt to their winch plates. Beyond that, JCROffroad and others have bolt-on hoops, but they aren't going to work with many types of winch plate, and may require some tweaking or customization (grinder, welder, paint) to make them work.
Ultimately, it sounds like you DON'T want a stock bumper with a winch mount, but want a bumper with a hoop and shackle mounts and other "upgrades." So instead of doing the bolt-on thing piecemeal and still ending up with an inferior setup, why not just buy a bumper that does what you want it to do and call it good?
