There are a bunch of 69 blazer specific characteristics to these vehicles such as the passenger seat belt placement, body coloured top, lack of rear top mounting plate, etc. Many of these items appear to be first year quirks that were later improved upon during the production run.
I am curious as to whether the blazer latch reinforcement plates were added on as well. My blazer does not have them and has the original paint underneath a bad repaint. Are other 69's missing these? Here are the items in question.
