The 2Dr Tail lights are about 4" longer then the 4Dr tail lights, So they wont fit without heavy modification's....

No company make's aftermarket/custom tail light's for the 1990-1993 Integra 4Dr's...

But you can do some tricks to the 1990-1991 Tail light's.

Like mine...





Get a bottle of castrol super clean (Purple power works aswell)... Remove the tail lights from the car obviously, Remove all wiring and bulbs... There's a white piece that you have to pry out to get the wires off... Take the tail's to the sink and rinse with warm (not hot or cold, but in between) water, Then add the de-greaser into the tail lights (throught bulb sockets)... Then add some warm water and slush it back and forth until the pink lines turn white... then set out to dry for about a day.

Here's some pictures of a friends (2Dr Tail lights i did).

Compare stock to this tricks.




It's easy to do and takes about 20 minutes total, The only hard part is getting the wires off the tail lights...
