maybe the same with the tops...they didn't want to be stuck with a warehouse full of unused tops....
simply due to availability....with no rhyme or reason? IDK....just guessing...?

There’s definitely a pattern and it’s documented on this thread. Flint switched from double to single walls and the early single walls used the non-pickup, external to the dash speaker whereas later run single wall tops used the pickup style speaker. Makes sense to switch to the pickup style in terms of stock but St Louis doesn’t appear to have followed suit and there’s no definite evidence of St Louis using single wall tops.

What I’d like to know is when St Louis stopped making the 72 Blazer relative to Flint. Flint assembled them until at least May of 72 and probably later. I’m not sure about St Louis.
