Hello:
Can anyone tell me whether a 1988 Honda Civic Hatchback DX driver or passenger door will fit a 1989 Honda Civic Si Hatchback? I need new doors on my 1989 Si hatchback and wondering if these doors are interchangeable for both these model years. Any help is appreciated. Thank you. Rick

 

Yes, but they will have crank windows if you have power.

 

Seatbelts the same?

I believe they went to door mounted seatbelts in 90-91.
