Re:
Got some rebas that may fit your bill. Bought them ages ago, refurbed them (lowers out, cleaned and greased, swapped out the faulty u-turn with a standard air spring set at around 100mm). Havent fitted the damper fully, as didn't want to fill.up.with oil and then sit idle.
Lowers are a bit scruffy, but cosmetic only, uppers are good, small mark near full travel is only blemish. Hold air, have a lockout lever somewhere. Can throw in a second set of lowers that need a clean inside. Top bushings seem fine in them, without a clean, cant tell about lowers (they were the donor fork for the air damper). I can throw in a set of replacement bushes too. Ones in the built fork are fine though.
