Kapish?

how did anybody notice this? I think a picture would be awesome! And kouki = S14 so how does this help? It could be a 98 S14 kouki sr20 or a 99 S15 sr20, which does not help identify...

I bought an eccentric throttle wheel to put on my s15 spec s with an sr20det conversion, but had no idea about this fact. So when I went to put it on it wouldn't fit over the bolt. Emailed the manufacturer to slag them but they told me the difference so I had to file out the hole.

I know it doesn't distinguish between s14 kouki and s15 but if the bolt is the fatter version then it at least narrows it down to a zenki.

Just a little tid bit.
