Ok. My 2005 impala base cluster is going bad and yes I know they are a problem with poor GM stepper motors, question(s) are... can I use a cluster not just for the base I car have. I guess one with a oil pressure gauge would need some sort of engine part to make it work. Mine has the temp(going very goofy), fuel(starting to go silly) and speedo(so far ok). An upgrade would be nice but I can live with a rebuilt unit as I have found online that all I need to provide is vin and miles on it(62,580)and they will flash it. Car runs FANTASTIC and smooth. I don't want to be w/o a cluster waiting for mine to be rebuilt and calibrated. Don't want [censored] gm steppers either. Thoughts? Thanks folks ! Have a great new year !!
