Replacement o-ring for speedometer KA24-trans - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Has anyone found a replacement for the speedometer o-ring? There is no separate part number in the Nissan parts catalog. I measured the groove on the speedometer at 24.5mm. The bore diameter in the trans is ~28mm while the o-ring itself is 1.5mm. I looked on McMaster, going with the 24.5mm inner diameter, and found a 2mm o-ring. But just to be sure, I wanted to see if anyone found the right replacement somewhere else such as Nissan's part catalog?
