Hey there
i have a electronic vdo speedo in my mazda 1000 ute, it uses a w57 gearbox wtih a vdo sensor that attaches to where the speedo cable used to be.Not cheap , but works same a factory. you may be able to get a sensor from a late model toyota that will fit , and be a cheaper option. The VDO part no i use is- 340 801 toyota hall effect sender.
cheers
