speedo change
i want to change the 85 mph speedo in my car to a 145 mph one
i want to know what car year would be best to get one from
i have an 85 iroc with an L69 5-speed and 3.73 gears
i have the rpo's E5Z- speedometer adapter delete
E9Z- speedometer key delete
and E7Z- unknown ( asuming that it deals with the speedo since it is between the other two
i want to make this as easy of a switch as possible :lala:
thanks
