I have an already blasted and bushings removed set of rear upper control arms for a 70-72 Skylark. Maybe 68-69 also. These are correct for non- heavy duty applications with NK stamped on them. These are from Texas and are not correct for a GS as I figured out however they would work but do not have as wide a flange on the side. You would be hard pressed to find a better set and most of the work is already done. Just install bushings and paint. Picture shows one of the set next to my old crusty original for comparison. Both sides are just as clean. $75 plus shipping.
I actually spent close to 8 hours over the weekend degreasing them cleaning off undercoating, blasting and removing the bushings from these. My originals will never come out anywhere near these ones.
