I have a 90 civic si with a b18c. I purchased the car and love it. It looks like one of the bolts that holds the rear bracket to the motor is missing. The motor is rocking upon shifting and deceleration. The mount is has port from looking at it. Does anyone know the part number or bolt I need to fix this? I can supply picture if need be. Thanks

 

If the bolt you are looking for is the one that passes through the front of the T-bracket and the back of the block, then the part number is 90190-SR3-000 and the washer is 90505-SB2-000.
