when converting your 96 civic 4dr to a 99 civic front end, dont you have to use the 99 4dr front end or are the 2dr and 4dr front ends the same on the 99-00 civics?

usually the 4dr front ends are about 2-4 inches longer than the 2drs, i posted an ad in a local forum and a guy is trying to sell me a 99 si front end, complete. then when i asked him if it would fit a 96 4dr, he just said "DUH"

does that mean DUH it does or DUH it doesnt, cause if it doesnt then why did he respond to my ad when i specifically said 4dr.

and if it does fit then why not say it does??...lol

any help is appreciated.
