Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Much larger than expected. Looks like it has everything you'll need to replace all of the seals on a GM AC system. Five stars for the product. Shipping was a little slow so I'd already purchased the two seals I needed from the dealer to ge the AC running. These are good to have as a backup and for friends.
