Need to know size of a nut please!

Rack adjustment lock nut - As highlighted below (and reference number 6). The rack is from a power assisted 90-91 LS integra 4 door or an EF8/9 CR-X.

I cannot get to this gigantic lock nut with the tools I have because the PS lines and cross member are in the way. So I might try buying a tool, but I won't have the opportunity to measure the nut before the next chance I get to go tool shopping, so if someone can tell me the metric size of this nut, that'd be awesome (it looks around 30mm). Cheers

measure the distance between the two opposing sides of the nut...

Oh well. I think I might just drop the cross member out completely to work on it. Thanks for helping Drew, Bennjamin :P I'll post the size for the sake of the archives after I get a chance to measure it.

40mm 6 sided. Honda special tool: 07916-SA50001. Thin frame flat ring spanner.

For reference, the tool is about $350AUD, which is why I'm going to MAKE ONE instead.

thats true. im a mechanic and the special tools are to stop back yard jobs, id take it to a honda dealer, but if you want to and you know what you are doing then go for it, but be carful!!!
