Date of manufacture - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is there some way to determine this from the numbers on the blazer or the frame? Some of the grease pencil marks? I was trying to find this date so as to reproduce the blue sticker on the driver door correctly as mine was deteriorated at that area of the sticker so I was unable to read it. I have the VIN and such, several grease pencil numbers on the frame and the body which I have good documentation of. Any help appreciated!

Mine has a date in grease pencil on the top of driver's side inner fender.

Did not have that but did decode the engine to July 10, 1970 so I think it was a date of July 1970, which I remember that date for some reason, maybe a mental note from the blue tag. I took lots of pics but never seems to be the exact one I need!

That sounds familiar!

Are there any kind of vin numbers stamped into the frame? Mine is so badly rusted, you couldn't see them even if they were there.

**bigdon-70blazer** · 02-18-2010, 01:07 PM

Yes there were on mine, on frame under driver and frame in engine compatment passenger side. Mine were both there and I documented these as correct.

Here is another big question... What was the total manufacture numbers or VINs issued by Chevy for the production run year of 1970? Reason being, my VIN numbers corresponding to the number it comes off of the line (the way I understand it anyway) is 86943. It was manufactured sometime July 1970 based on the engine codes so that would make it a fairly late run as the new model year is getting ready say August - September time frame. Any ideas on that? Doesn't make a hill of beans difference but just fun checking out this stuff. I did count the numbers of trucks and related and came up wit a total of 43827 but there are lots more others than that.

Please post a pic of the blue decal after you redo. Would love to see how it turned out. Thanks,

How come the blue door decals are being re-done? What was wrong with the ones on ebay?

**bigdon-70blazer** · 02-19-2010, 07:43 AM

I am not redoing the blue decals from ebay, those look just fine to me. I ordered one and should be here soon.

I read sometime ago on this forum that the SPIDs were typed on an IBM Selectric electric typewriter. Or was it that SPIDs were best duplicated on that kind of typewriter -- being closest to the kind of industrial machine GM was using at the time?
