What dash cluster was originally in your Blazer ; the standard gauge cluster w/o tach? Did you have to do any wiring changes (other than running new tach leads) to install the tach cluster? I'm trying the same swap,but the new tach cluster wont function at all.blazinred87 said:I installed the tach cluster in my truck. I like it much better. Anyways, I didn't find a white faced gauge kit. I did the next best thing, and bought one of the stainless overlay kits. Not what you were talking about, but it sure gave my gauges a nice constrast for a total of about $18.
