It's a cross sill like Richard said. Not sure if they are reproduced now, but when I did my Blazer I used a pickup truck cross sill. I seem to recall the only modification I had to do was at the area where the hold-down bolts go through. You can see in the picture there's flat indentations where the bolts go that I had to put in. The pickup truck part is flat in this area.

EDIT; I checked Bill's trucks (near me) and that part is now available for the Blazer. Check out page 153 in the link below part # 27-5117-A
