Truwsteer Steering Box Quality

Hi folks,
my Wolf 90 steering box is destined for the recycle yard, the worm bearings are through the hardning on the upper bearing face of the worm. I note LRparts.net are offering Truwsteer boxes (QAF500110) as a replacement for the QAF500030 4 bolt ADwest box. Does anyone here have experience with these please?

Thanks

Ian

Quite a lot about them on LR4X4 site.
