Those are the right numbers. I got mine from AZ a few weeks ago. The bolts are still 10026678. They used to be a couple bucks each, but at GMPD they are around $9 now. I got the rear bolts at AZ, same part number, but they came as a 'sway bar repair kit' made by Duralast, part number SL224 at AutoZone. Don't use their bushings of course. Or you could get grade 8 bolts from your local harware store.
Bill, I got 3/8" nylock nuts and test fit them fine...but is 8mm better? That old post says 8mm, but the kits themselves have 3/8" bolts.
I couldn't seem to find the front kit on the website, but you have the right number.
