VIN or cowl tag decoding

I'm going to start looking at at some 70-72 GSs' for a project car and I want to get some tips on how to read the VIN or cowl tag to make sure its a real GS.Any help would be appreciated. Thanks

 

Here's the very basics in identifing a 1970-1972 GS by VIN -

1970 -
434 - GS350
446 - GS455

1971 -
434 - GS

1972 - (2nd letter in VIN must be a 'G')
4G - GS

 

thanks a ton Marco.Your website is very informative also

1972 Sun Coupe

 

Well right now it's a project car it probably won't be done for a year or more.But it is a GS 350,was dark brown with white vinyl top and interiorbuckets and console,no A/C,N-25 bumper.Right now its in a million pieces,and unfortunatly it probably won't be ready for the BPG nats in August .

 

Oh yea, John your car is beutiful and I'd like to see a picture of that carpet your talking about.

 

Thx for the info and compliment. It just got painted a couple months ago, it was a little rough before. Interior is under construction, in fact I am doing carpet today if it stops raining. Red again for sure.
If you send me an email I can send you my Sloan info, order form and window sticker from Mike Trommetter. I found the build sheet under the pkg tray but it is rough because of a rear window leaking and subsequent rust.
It has a 350-4bbl. single exhaust as of now.
Did you get Sloan info for yours?
