I don't know what parts you need but have you looked into what signal is required by the skyline dash and what commonly fitted electronic drives (and their signal output) are adapted to your type of gear box?
There are a few convertor boxes out now that will let you use pretty much any electric drive with any speedo and also have adjustment to get the speedo reading correctly. I purchased this speedo convertor to allow an S15 cluster to be used with my CA18 one is sinewave and the other is squarewave. http://www.dakotadigital.com/index.cf ... d=59/mode=prod/prd126.htm

I have a remodelled R33 skyline dash that I am fitting into my datsun ute. I have priced a cluster and and individual gauges and it is cheaper to buy the skyline cluster right out. I have already bought the cluster and I need to convert my 4 speed transmission from mechanical to electronic. Does anyone know what Speedo drive to use for this?
