I have 3x early 2002 4 speed gearboxes and 1x e9/Bavaria 4 speed box for sale, all stored inside for at least two decades. They shift through the gears fine and the input shafts spin smoothly but these haven't been installed on a car in a very long time and are priced accordingly. Two of the 02 boxes have complete shifter assemblies, the other is mostly there. E9/Bavaria box has no shifter asssembly. Again, all are early style with the round slave cylinder and the bigger 4 speed is the removable bellhousing type.
Will add pictures tonight. Priced at $100 each, will accept a lower offer for multiples or the whole lot.
