I joined this forum for one reason, to thank Bob T for saving me $500. Thank you, Bob T! The instructions you provided made the entire process of replacing the stepper motors quick and easy - 45 minutes from start to getting the speedometer back in the Suburban and another 20 to tweak the gauge pointers. I set the speedometer pointer by comparing it to a GPS while driving.
Reference #10: a right-angle pick releases the tabs easily.
I replaced all six steppers for less than $45 (including the shipping) from digital dash solutions on ebay:

I took several dozen pictures during the process. I'll post some if there is interest....
