You dont have to get a 17mm bolt..that is only the size of the head.

Get the proper diameter and length/hardness and a new nut and you should be good to go.

Try mcmaster.com they may be able to get it to you quickly.

 

^^Do you know where I can find the right diameter/length/thread pitch for the bolt? I tried callling nissan/courtesy, they are all closed. Actually, just found this, can you see if you can confirm this is the right bolt?: http://www.courtesyparts.com/350z-pa...5_800_804.html

I read some threads and they recommended grade 8 for the bolt, and type c for the nut. Just want to confirm, thanks.

 

can't find the thread pitch/size/specs. So I guess ill have to call courtesy again tomorrow when they open and ask for the specs. Assuming they dont' know what the specs are, can anyone who does still chime in? Thanks.

 

It helps if you look for the proper size bolt, also call around for a shop that specializes in bolts. 12x1.25 is stock , don't know the lenght but you have the strut body to measure. 12x1.5 will also work just fine since you have to get the matching nut for whatever bolt you buy.

 

^^Would knowing just 12x1.25 or 12x1.5 be enough to find a bolt at either mcfaddendale or mcmaster? Or would I also need to know the thread pitch? Because I think some places I called had those specs, but I assumed the head needed to be 17mm, which none of them carry. I don't think the length would matter too much, as long as its long enough. I kinda know how long it, based on eyeing it lol

 

Yes

Doesn't matter at all for this application, i think the ones on my coilover is 16mm. Odd size head, but i needed a longer bolt for my setup.

Feeling generious, stock lenght is 78mm. You will need 80 to 85mm since you will need a add a washer under the bolt head.

 

alright, cool. Thanks for the help. I guess ill have to stop by those shops and see if they carry those sized bolts. And just to confirm, either grade 8 or higher for these bolts, and a type c for the nut?

 

^^btw, those sizes are in metric right? Cuz some stores didnt have a metric system, while others did.

 

I will bet you will never find a 12x1.25 bolt in SAE

 

^^Just saw the rest of your response, didnt show up the first time. Thanks so much bro :]

 

all i can say is...wow...please dont ever attempt working on your car again haha

 

got the bolts and nuts from mcfaddendale thanks for terrasmak. Thanks a lot bro. Installed them and now they ride just fine. Im really happy haha. Btw, for the coils I got, I need to take off the wheel everytime I want access to the top hat, which would allow me to lower/raise the height. Would I need to take off the bolts holding the spring bucket and spring just to get access to the top hat? Or is there a tool that is supposed to come with the coils that lets me adjust the height?
