I got these back from Apple Hydraulics in NY two weeks ago. I was on vacation in Florida last week so I haven't been updating or working. They did a fine job. It was a little over $800 to have them rebuilt with shipping. One of them was not repairable so they replaced it with one of their cores which cost me a little extra. They came back primed, filled with oil, and with new bushings installed. It was about two weeks turn around time. I chased the female threads with a tap shown in the photo and I will be installing them as soon as I find my bottle of blue loctite. They will be going in with new grade 8 bolts.
