You can get the socket off of ebay for like 12 bucks or something. It's just a regular socket with a slice down the side for the wire. You're probably going to need some sort of uni-joint extenstion(think that's what they are called) that way you can get it in position right. I just buy the stuff from pep boys then return it later and claim i didn't use it.

I have an 89 Civic HB, did my o2 sensor about 2 months ago. Went to a JY, found an o2 sensor on an older 88-91 civic/crx, one wire style just like yours. Pulled it, paid 5 bucks for it, and put it in. Works fine too, SCORE!! As for what autozooen sells, they sell a universal one that may require you to cut the wire and splice it, and they sell one that has the plug on it for about 20$ buck more. The one with the plug is better quality. You can find these on ebay too.
