Thule (http://www.thule.com) used to have a rack system that worked with
the '92 - '95 Civic hatchback, but it is no longer available. Thule (and
Yakima too, for that matter) don't sell complete racks, you have to buy
the individual parts to fit your car and intended load.

For your Civic you would need 4 "400xt Aero Foot Pack", these are the
feet that sit on top of your roof, 4 "LB50 Load Bars", the bars that go
across the roof, on top of the feet, 1 "167 Fit Kit", these are
essentially rubber pads that mount on the feet and match the contour of
the roof / rain gutter, and finally you need the "short roof adapter".
The problem is that the short roof adapter is no longer listed for the
95 Civic Hatch. I don't know if they discontinued it or if they just
don't recommend it for the Civic any more. If you are interested, I can
see if there is a part number stamped on my short roof adapter. That way
you can find out if Thule is still selling them, perhaps you can find
used ones.

Once the above is secured, you need to get a carrier for the load you
need to carry, bikes, surfboard, canoe, kayak etc. These are easy to get
from Thule.

If you go to a Thule dealer, tell them you have the 4-door Civic, and
they should be able to get you every thing you need except the short
roof adapter. Then get the short roof adapter used.
