ok....how or where would someone find out weird stuff relating to the correctness of corvettes. like the picky ncrs things. would the judging manual have things like that, how do i get one? i mean, when i want to know what color my oil filter was originaly, or what color my intake should be, or if my floor mats are aftermarket or original, where the heck does someone find that info. basically i want a " this is what your corvette looked, sounded, and smelled like when it came from the factory " book. Is there such a thing?

Also.....if a part is NOS, does that mean that it is 100% correct as the part was from the factory? i'm thinking no.

 

What your looking for is the "Judging Reference Guide" for your year form the NCRS. It will answer almost any you'll have

NOS is Suppose to stand for "New Old Stock", in reality, folks use it a many different ways - "buyer beware".

 

yeh, i knew that nos stood for new old stock, but what is the definition of old. if someone owned a part they bought in 86 for a 75 vette, is that an NOS part ?

 

"Correct NOS " is the part # that was specified for use in the AIM. Normally
that part# if used in future models is continuely produced till its superceded by a service replacement part. Both the assembly manuel part
and the replacement part can be NOS but the AIM part is the correct one.

 

Actually, the NCRS publication that will help you the most is,

"1978-79 Corvette Technical Information Manual & Judging Guide"

Also, Prince's restoration manual has a lot of similar information, ie a detailed description of what things looked like from the factory.


I'm thinking of this one===>>> http://www.amazon.com/gp/reader/0760...33#reader-link

 

Ask Paul Borowski. I swear the man is an idiot savant on that type of stuff.. I gained a ton just listening to him at CI.

 

Look at NCRS.org. They have a page with definitions of varous terms. Generally NOS means New Old Stock and, If you're lucky, a NOS part will be an exact duplicate of your original part. If you're buying NOS, you should hope that the piece will be shipped in the original GM/AD Delco, etc box. If you don't get the original box, there is a danger that you're not getting the real NOS part.

...now, if you buy a NOS part, it still may not look exactly like your original part. GM sometimes made changes to vendors(who made the original part), or bought the same part from different vendors. Also, I've always suspected that vendors who had slightly blemished parts would sometimes sell them to GM for inclusion in their spare parts inventory.

OEM is original equipment manufacturer. I think OEM basically means the part will fit and work. It will not necessarily look like the original part.

Also if the part is NOS or OEM, this means you can expect the part to be of /hope the the part to be of good quality. This is not a 100% guarantee. Generally most NOS parts are of good quality (although they often could be better.) OEM parts can be less reliable, they can be made under license in third world countries. They should be made to original specifications however..
