Re: 1970 Medium Duty Investigation
What are you trying to decipher? A picture of the spid would tell you more about the actual truck than the vin. Unless you're trying to figure out build dates and which plant it came from.
I got a gmc parts book in storage I could dig out but hopefully somewhere here will chime in.
