i'm looking at kits, and on company says there's two different hanger styles, has anyone heard of this?

 

yup. there are actually 3 different ones i believe. i have a drop kit with the 99-03 short hangers and my truck has the longer ones with 3 holes. i gotta get rid of the hangers and get a new set. major pain, wish i would have known before purchasing. are you going to get a carrier bearing kit or try and use the factory one?
