I had someone measuring a set they had on there cutlass and they measured and 6.5For the front bumper, your car would need absorber GM p/n 22016704 or 22018157 or aftermarket equivalent, if they even make one. Not even sure. If you find new ones, they don't come with the little rear "L" bracket that a nut holds it onto the back, and a bolt goes up through the frame to hold the rear part of it stable.
I never measured them. I normally just go by part numbers. If I get out to the shop today, I'll take one out of the box and measure it.
