Cheap a schips but works well.

check out the hellfire website he managed it using a spring-loaded wheel type affair.

Our speedo isn't cable driven, its electronic, although the methodology of running it from a rotating part should be the same. We manufactured a sprung aluminium bracket to run the speedo pickup off the diff output. The only problem you may have with a cable driven speedo, is correcting any reading errors. On an electronic speedo, this is done by using a speedohealer or yellowbox. Might be slightly more difficult on a mechanically driven speedo tho. HTH
