1993 NH 2120 (the best), 1974 MF 135 (sold, but solid), 1947 Farmall A (bought, sold, bought back, sold again), 1956 MH50 lbt (sold, in 1980, darn it)
Have you ever changed a clutch? Are you certain you need a new one? Have tools? Experience?
Everyone's gonna tell you to get a shop manual. It's not hard (except maybe aligning the pieces when reassembling) but heavy and dirty. And rewarding.
