Worked!
Replaced reservoir and pump on my 1997 GMC Sierra. Reservoir was exact fit but pump was not...although it worked just fine. Specifically the fill connector coming out of the pump was not in the same exact location so the pump wouldn't set into the reservoir like the original one did. Wasnt a big deal once the top casing of the reservoir was snapped back on which helped hold the pump in place.
