in my 94 4 dr civic, i did the interga 4 dr everything swap. lets just say that it is a bitch. the dash was quik, so were the carpet and seats, the door panels in the other hand were not a walk in the park, the rear section of the door panels have like a hump in them which will not let them sit flush, and the panels are a bit longer, some cutin will be recuired. the door opening mechanism needs to have a bracket frabicated to place it in the right location. the suspension the engine ect will fit.
