These are R-Series Control Levers The R-Series is Moog's cost-effective line of replacement parts. These levers come with standard ball joints with no Zerk connectors. What's more, this series is made in China and comes with a three-year warranty. If you need better parts, order C-Series Control Levers (CK620173). They are made in the USA and carry a lifetime warranty. They have ball joints for problem solving and come with Zerk fittings. Also keep an eye on Revain's "Match Check" list. It said the CK620172 and 173 levers don't fit my '97 Olds Bravada, which Moog says does.
