The speedo drive on the very early Subarus were cable driven from the gearbox to the drivers dash board.
The cable is actually made up of x2 pieces, a short section which screws into the gearbox which then joins a longer section which comes up from the gearbox, through the bulkhead and into the back of the instrument cluster.
These have now been discontinued and are no longer available as a new part. With this in mind, RCM have replicated both parts which perform exactly as the original part did.
For the lower section, please see part number RCM3439.
For both sections combined please see part number RCM3439-3551.
