88-91 Honda D Series Engine Mount Hardware Kit
Complete OEM-spec hardware kit for replacing all engine and transmission mount fasteners on your 1988-1991 Honda Civic/CRX D Series swap or restoration. Every mount on the vehicle is covered — rear trans bracket, passenger side trans mount, front mount, and driver side mount — so you can torque everything down with fresh, correctly-sized hardware instead of reusing worn or rusted factory bolts.
All fasteners are JIS spec, matching the head and socket sizes used on factory Honda hardware — no need for the 13 or 15mm sockets here. Bolt lengths are closely matched to OEM, with minor variances on some pieces due to sourcing. All hardware is a yellow zinc finish.
