Why not recalibrate an existing cluster with the HPT software instead?

I tried with the cluster but there's no way to recalibrate plus you can't get replacement motors for the gauges that are bad other than junkyard parts and I've tried 2 different one already and both have issues so I'm going to 3d print a mount to house a full set of aftermarket gauges I already have but the speedo is a mechanical drive and they don't make an electric version of those particular gauges

If this is the 99 you're talking about, it gets calibrated via the tuning software. I've done it many times.

the mechanical style speedo housing will not work, it drives off of the right side where as the tahoe drives off of the left.
