After months of talking to the Moog factory rep he told me they were going to come out with a upper ball joint for a C5 Vette in late November. I spoke to him a week ago and finally its available. This part number IS good but it may take a little pushing on your part to get your parts store to order it. Or call O'Reillys in Smyrna ,Tenn (615) 793 7600. Its $76.99 plus shipping there. I spoke to a guy named Adam. He found it available. Moog factory told me they had 23 (minus my 2) in the Distribution Center there in Smyrna. I hope this helps the people looking to use Moog parts.
