I do the rebuilds, yes the vac advances are getting crazy. I have no issues with cardone at all except if you need a specific curve good luck from the parts stores they are kind of set in the middle of a span kind of like one will fit many applications, that is why they do not have tags/numbers on them. I had no idea they would rebuild yours to specs. Good to know. I specialize more to each application since as far as I knew there were not many shops around that could do that any more with oem parts, and specific curves.. Any one ever need info hit me up I am retired and have plenty of time to help people out.
