Where can I find a knock sensor for a 92-96 h22a engine?

[hornyhonda]

I got my engine back from an engine builders and cant for the life of me find the knock sensor. Its not in the back of the block also so I need to get another. All the ones on ebay appear to be for the later models of prelude and accord. Anyone know where I can find one to fit the 92-96 h22a engine?

Thanks
