I have a few, new-in-box sets of 16 valve stem seals that fit many of our Buick engines. NOTE: These are sets of 16 seals, NOT the sets of 8 currently being sold by most the major vendors today. These are quality, made in U.S.A. seals in the original packaging. They fit the following Buick applications: 1968-1981 Buick V8 350CI (5.7L) 1967-1969 Buick V8 400CI (6.6) 1967-1969 Buick V8 430CI (7.0L) 1970-1976 Buick V8 455CI (7.5L) No machining is required to install these seals. The price for each set of 16 valve stem seals is $25, INCLUDING shipping in the U.S. Again, I have several available. PayPal (sorry, no fee only), personal check or money order are all fine for payment. Thanks for looking.
