I just bought a set of 2.85 t-case gears from Mark Hardman at the beginning of last month and have since had them installed. At the time I was working out acquiring a set from Mark, he had said he had two sets left. One of them I got, the other (last I heard) were possibly being purchased by somebody from Norway, but Mark was unsure if the sale was going to go through. Bottom line, if he has any left, he only has one set left. I wrote Mark last week to find out whether that last set of gears was still available. I was planning on posting his response here once I got it. If there is still a set left and if they fit your t-case, I highly recommend it. They ROCK!
