For those of you who have replaced your radiator in `98 Civic or similar, are there any tricks to fitting the new rad in? My old one came out fine, but the new one doesn't seem to fit in low enough to sit under the under the front sheet metal. Oddly enough, I tried the original rad and it does not sit low enough to either. Even with the bottom rubber mounts removed, they still don't fit. Obviously, I'm missing something here. Suggestions??
