I consider myself at least a step above a slug but I’ll be darned if I can figure out how to find the correct gauge cluster to order for Chris to program. If there is a resident parts guru who can direct me to the right one, I would really appreciate it. I’ve gotten more confused the more I read and totally understand why Chris could not ever compose a list of everything we may need. I tried going to my local GMC dealer and of course they will only order off my VIN and the Denali cluster doesn’t jive with my VIN. The oil catch can research was like first grade class, this...to me is worse then college Trig.
