WRONG.
Wheels from a 2001 s10 will not fit directly onto a 97 Blazer despite them being both 2wd.
98+ s10s use a slightly smaller hub and thus the wheels have a slightly smaller hub opening. Both models 94-97 and 98+ have the same 5x4.75 bolt pattern but with the smaller hub on the 98+ wheel it will fit on the 97 VERY TIGHT.
I have seen people post different strategies on how to take a little aluminum out of the hub opening on a 98+ wheel in order to fit it on an older s10. In the past I have just YOLO'd it and horsed 98+ wheels on older trucks, not a very good idea. You'll need a big ass hammer to pound the wheel off the hub.
