i have a 1200 sedan and have recently done a ca18det conversion with the s13 5 speed, i have a few questions. ive done a search on this site and to use the original speedo i need a mechanical speedo driver from an early skyline and a speedo cable from a bluebird, is that the r30 skyline? and also the cable, do all bluebirds use the same speedo cable? i just need some details before i start ringing around
