Well the gauge cluster I was hoping to put along with this dash.
And looking up info on gauges I came across this information in frequently asked questions on the matter. My vehicle currently has a cable drive speedometer. How do I set it up to work with a VDO programmable speedo?
If you take your speedometer cable to a local speedometer shop, they should be able to install an upper end that will match the 340-011 pulse generator. This is the easiest and best way to hook up an electronic speedometer in a vehicle that was equipped for a mechanical speedometer.
So, it's given me some hope that it could work.
