Have you considered finding truck doors and cutting the window frames to make them into Blazer/Jimmy doors?
Especially since that is how the Blazer/Jimmy doors were actually made at the GM plants.

Significantly increases your chances to find good original doors, since so few Blazers/Jimmy were made versus trucks manufactured by GM

That is what I did. Found great truck doors in Arizona, then made them into Blazer/Jimmy doors. There are instructions in some post on the forum. Including the original instructions/work sheet used at the GM plants.
Really not difficult to do.
