Converting Manual To Power

I Have A 1999 NBS Silverado Ext Cab Pickup. I Am Looking To Convert My Truck With Manual Equiped Items (seats,windows,locks,mirrors) To Power. I Am Looking To Use All Factory Parts. Anyone Know The Items I Am Gonna Need Or Have Part Numbers. Any Help Would Be Greatly Appreciated. Also If Anyone Knows Anywhere I Could Pick Up The Parts I Need Speak Up!. Thanks
