I didn't see a pic of the front air dam. And it didn't say what years its for. I've seen some sin ugly one for the 94-95 but there is a nice looking one for the early SC's.
The rear bumper fits fine. The front you'd have to get a new hood, header panel, headlights, and bumper. All from the earlier cars.
There's a guy on here with a 94 LX that had an SC motor installed and the front end conversion back to early style and the early rims and early bumper. I'd personally keep the late model wheels if I was him, but he bought it that way.
