2000 Blazer ZR2 Winter Truck Build Part 9: Ultra Rare Half Bose/Half Delco Stereo Option?

Part 9 starts off innocently enough. I remove more mouse nests, another dead mouse, more urine-soaked insulation... you know, the usual. Then I discover that my rear speakers appear to be set up from the factory with one Bose speaker and one Delco speaker. I never really resolve it, but do at least come up with a solution. Oh, and I reach an important milestone by finishing the heater box restoration.
