which speedo do i need i have the mk3 polo with the clock on not the revs want the rev and speedo anyone point me in the right direction

Genesis or GT.

does it have a digital odometer or is it a normal anolog type. will i get the rev part working or will i have to add something to the car for that to work

The odometer is the same mechanical type, I believe anything with any type of clock has a trip odometer too, which is also mechanical. The speedo/odo part of the unit is separate though so you can easily swap it over.

Wiring for the rev counter is already there :)

great stuff dont know if anyone is selliong one do you at all

Don't know anyone myself but they come up in the for sale section fairly often on here, looking at about £20 I think for the tacho clocks, just keep an eye out, and no doubt ebay would be good place to look.

cheers spot on advice gonna get something from a scrap i think
