Did i get the wrong regulator

[04Roadglide]

2004 liberty. My right rear dropped by itself overnight. I shopped around and decided on Rockauto.com. The regulator I picked claims it has a limited lifetime warranty. The picture on the website showed what I think is a new style? What arrived is exactly what I removed and has a long history of failure.
I couldn't find any way to contact Rockauto and ask if there had been a mistake.
I went ahead and installed out of frustration!
Would someone know if there actually is a new style using the same part number

Thank you Chris

The old style is no longer being made. Of course, the bushings on the upgraded LCA can still fail.
