My friend owns a 1989 Civic Hatch Si.. and his gas tank just started to leak so he wants to replace it... the question is....is there any other gas tanks we would be able to put on??? would a 92-95 civic one fit??... or Would the 87 Integra gas tank fit???(cuz we got one in his back yard) or would a tank of a crx fit??? is there any difference??? I thought all 88-91 civic,crx,4doors used all the same parts?? is that true or is the tanks different??? Thanks a lot guys
