I have to replace my instrument cluster on my 08 gmc acadia fwd slt . I suspect that my cluster is not original because most of the warning indicators are not lite wgen started and the mileage is very low.I understand that these units are plug and play meaning they will when installed maintain the donor mileage and not that of your original cluster but you can clone it for a charge to your original one . I have a US version cluster miles per hour primary vs klm per hour , my question is are these clusters interchangeable (US and Canadian) because I live in Canada I would like to use a primary metric cluster . Also I am having alot of difficulty getting the proper oem number for my original vs cluster and a Canadian replacement the oem numbers I came up with with the help of Gm Canada is 23161137 and 23161238 but there are so many numbers and variations pls help if you can ....javindra.spencer@gmail.com
