my speedo has no rev counter can i just plug in new speedo in with the rev counter and will it work. then i can get speedo rings an blue leds at the same time.
YES all speedos are interchangeable 120/140/160 mph units
couple of mins to swap over - will take a bit of head scratching to figure out the correct angle to remove the clocks from the dash but you'll get there in the end!
usually ten a penny on ebay (ive bought about 5 sets in the last year alone) if ur lucky u can get em for about £20 upwards.
Mileage will of course be different on the new clocks - only way they can be programmed is using a "mileage correction service" - see ads in auto trader or similar... VX can NOT reprogramme dials unless they have less than 100 miles on em!!!! Personally I just made a note in the service history for any future owner etc.
