Are both rear upper control arms the same?

[BuickMike]

I took off all of my rear control arms amd marked them L and R respectively. After bead blasting the uppers I realized that I blasted off my markings. Doh! They have different stampings on the top, however according to GNPartsDirect they are the same part number. Anyone know if there is a left and a right?

they are the same right or left , just when you put in the lowers make sure the swaybar holes are at the axle end and the sway bar bolt reinforcement bracket is installed .
