Shifters for the '90-'93 and '94-'01 are shaped differently, like so:
The single bend is for '90-'93 and the double bend is for '94-'01. Not all companies make both versions, usually they do one or the other. I know that skunk2 makes both, and B&M makes only the single bend kind but passes it off for all Integras. It also tends to rattle against the exhaust piping so I don't really reccomend it.
The skunk2 can be purchased
here for $121. A bit pricey but it's a really nice shifter, as seen in the picture.
