Deadhead, thank you for the props. We're glad you are finding the decoders useful and very pleased at the number of people that have found the resource useful.

We knew about the Blazer VINs when we put the decoders together but left it off to save space. It was just the one year and only on Blazer models, so we figured not enough affected to include it. We kept to the essentials so that the characters and boxes could be as big and readable as possible. We also left out things like the starting sequence number of 800001 for the 1969 model year and 600001 for the 1971 model year. But your absolutely right, First year Blazers had a B for Blazer as the first Character of the VIN.

As far as your 654572 Blazer build date. Lucky it's a 1971. I can only do this for 1971. Any other year and we would have to do it the hard way. Checking blue door stickers, Engine date codes etc. against the VIN number in a made/collected database. But for 1971 I have some documentation from GM that helps a lot. Your Flint Blazer 654572 was built on assembly line 2 on June 17th 1971 give or take a day or two. I estimated the date. All I really know is that the last light duty truck built in flint, line 2, in May 1971 was 649411. And the last LDT built in Flint line 2 in June 1971 was 658369.

Hope that helps and thanks again for the props.
