It's either 32 mm or 36 mm. I could be mistaken but from what I've read, it depends on whether the car was made in North America (32mm) or Japan (36mm). At any rate, I am planning to buy a 36 mm so that I'll have both.

I have various write-ups for doing axles considering I've had to do them already. I have to do it again, too! Grrrrrrrr... However, I have a Civic. I'll email you what I have once I get it altogether (there are some additional sites for the Accord that I have at my disposal). I have the Civic Helms manual, though, so I'm mainly going to use that.
