Help for all of you

[whew41]

I have put together a cheat sheet for all to you. Use this sheet when you need to understand when someone abbreviates a phase and you do not know what it stands for. Now my no means is this list complete. If you knwo of additional items let me know and I will update the list and replublish it for all..

If you would like this sent to you please email me with your request and what format you would like it in.

Thanks E,

I started to add

FGDSSOBPO, for atrificially induced wiring problems, but I was afraid of the auto censor...

WIll

[whew41]

Thanks for the additional items they have been added....

[alissa280z]

HAHA I had an IPO! Thanks for the list... looks like it took you a while!

[Darrel]

Another one, but it's for those who have someone telling them something when they have no idea what it is they're talking about.

STFU

[Dropkick]

Ok, this may be dumb. I know that NOS is OEM Nissan parts... stands for what? Nissan Original ______????

[Darrel]

it's a generic term for any parts that were made by the factory for any manufacturer.

new old stock

[whew41]

Ok, this may be dumb. I know that NOS is OEM Nissan parts... stands for what? Nissan Original ______????

NOS = New Old stock

OEM = Original Equipment manufacture

[whew41]

Another one, but it's for those who have someone telling them something when they have no idea what it is they're talking about.

STFU

Well since I do not know what "STFU" until you tell me I can't add to the master list

[EScanlon]

STFU = Shut The Frak Up (Thanks to Battlestar Galactica!)

NOS = New, Old Stock Term referring to an Old item that used to be a Stocking item, that was never sold originally. Most commonly refers to items still in their original packaging from years ago, or that have never been installed / used.

CZC = Classic Z Car (Club); mainly THIS site.

IZCC = Internet Z Car Club (Zhome)
