4speed,
A company called SuperPro makes adjustable length end links and I spec'd a set that fits directly onto the rear of a stock H3 but is roughly 2" longer (when centered) than stock. They make them in overall longer and shorter lengths as well. They may not be as strong as a 1-piece steel link but I haven't had a problem with them as of yet, on or off road. They also have greasable ball joints.
If you want the info on mine I can try to dig up the part number, though I was upgrading dozens of things at the time so I might have lost/deleted the info, because I can't easily find it now.
I had a helluva time removing my stock links too even with LPS 1, and they only had mild surface rust. I got them off without cutting, though the threads did get a bit damaged. They were going into the trash anyway, because they somehow flipped over and got bent on the frame because they were too short for my mild lift.
