That and there is only a "T" on each side of the firewall, not a "2T" like it should have. Does anybody have any input?

Steven, The T is correct for your trim level. Blazers were either base/standard trim or CST trim. There was no mid level trim on blazers, so no 2T should be found on blazers. A "T" would be for standard trim and a "4T" for the CST trim.
I have been finding this to be completely constiant on trucks also. Nothing or a T for standard trim trucks, 2T for Z62 mid level trim trucks and 4T for upper trim level trucks. I have found 4T on both Z84(CST/Cheyenne) and YE9(Cheyenne Super) trim trucks.
Can't tell much about your engine/trans codes. The engine code looks like S9A, which could be short for LS9AA. Maybe the L got worn off or was never there. Can't tell much about the trans spot. Very nice blazer you got BTW.
