Here are the part numbers (you may want to double check them, just to be on the safe side)...
Summit White handles:
15066575 Front LH
15066574 Front RH
Onyx Black handles:
15745149 Front LH
15745148 Front RH
Both have keyholes on each handle. Best bet is to order from gmpartsdirect.com, you can probably get them for under $100 per set.
