This 60 piece kit replaces the hardware located on the chassis under the hood of a 1988-1991 Civic/CRX. This includes all of the 10mm bolts, strut tower nuts, and upper control arm nuts in your engine bay using OEM style yellow zinc plated hardware similar to how it would have came from the factory. This kit DOES NOT include hardware for the engine & transmission itself. See "Product Info" for the list of specific hardware that this kit replaces. As always, shipins is free in the continental U.S.
