Hi all. I just converted from '94 ford to Gmc. Love my new Denali and loved my old ford too. But is there a better way to search parts other than the gmc parts for interchangeable years instead of looking up several years to see if the part numbers are the same? I found parts that fit other years but if I go to like 2008 those part numbers are the same too but we're not listed under 2011. Like under 2011 it would say fits these vehicles from 2011-2013 but if I change vehicle type to 2008 it had same part number too. I'm looking for back up sensors and interior molding parts like for center console. Same part number for the 2008 Yukon Denali but wasn't under similiar vehicle list when the 2011 was chosen. I have some broken part issues and if I had a full scope of the years covered like 2007-2013 I can search junk yards if they have those years in their inventory. I think, but not sure some parts will fit from 2008-2013 Sierra, Silverado, Yukon, Escalade and Denali options. Any help would be appreciated. Thanks
