There is no short shift kit available for the 98-02 Accords except the PSPEC(which I own) and the Lean Racing, good luck getting a hold of either one. I heard through the grapevine that TWM may have us in the works for a full short shifter.
And as for adapters, they don't provide near the feel that a full shifter does. Having driven both on the 6th Gen Accord(98-02), there is a difference. I'd wait for the opportunity to get a real shifter, PSPEC or the like.
