Hey guys, this is my first post on my350z so please refrain from telling me to search ( spent a good time searching, must be doing something wrong). My car has just about every Bolton except plenum spacer so I said what the hell and purchased one off of a forum member. It did not come with hardware so I did some research as to what I need myself.
18 M6 washers
11 High Strength bolts M6 x 1mm x 35mm
3 High Strength bolts M6 x 1mm x 55mm
4 High Strength bolts M6 x 1mm x 70mm
8 Strut Bar Spacers (350Z only)
4 Strut Bar Washers (350Z only)
6 Iso Thermal Plenum Internal Spacers
I have the six internal spacers so the only thing that stumps me is the size of the strut spacers/washers. Any help would be greatly appreciated, if this has already been covered i'm sorry I could not find it.

edit: forgot to add it is a 5/16 basic plenum spacer

 

I've got mine sitting at home (didn't need them with a Cusco strut bar), I'll get you the dimensions when I get off if no one responds by then.

 

Now you have learned that used parts without hardware is seldom a deal. Hardware is unique and you cannot pickup at Home Depot or auto parts store.

Size of spacers for 5/16 inch spacer? Believe they are 5/16 inches.

 

Advan thanks so much.

 

Hit this link, scroll down to the second from bottom, that's what you need

350Z 5/16" Bolt Kit

 

I'm sure I can get the same bolts for under $10. Do I specifically have to buy motordynes?

 

That all depends, i don't know how important the types of bolts they are, stress, threads for going into a fairly critical engine component.

If you don't need them all, i'm sure you can call Tony and see if he'll sell you the ones you do need.

 

Will do, thanks.

 

We have bolt kits listed on our website just for this situation.
