Well, I can't find any info on these. They're using a different P/N than what it'* reffered to as with its drawings. I was able to dig up the last 2 revisions (the first main redesign with the torque limiting metal inserts, and the metal carrier design). The metal carrier revision is still showing as being used on product... so I'm not entirely sure what'* going on - there'* been an obvious price increase, as well as a new part number... I wonder if they've added something to the kit?
If you talk to a parts guy at a dealership (in person), they might be able to see if there'* something else included in the package, or at least get some notion of what'* different....
