No.Actually I got my facts screwed around. The donut you are looking for has a 16" steel rim. 16 X 4" to be exact. G-bodies that came from the factory with 15" wheels used a T155/80D16 tire. TR,H/O,442,MCSS and GP 2+2 are the only models that came with 15" wheels. Cars with 14" wheels used a 15" donut. RWD B-C-D bodies also used a 16" donut but those wheels are either a 5 X 5 bolt pattern or a dual BP wheel. The dual pattern will work but isn't PC from a restoration POV. RWD B-C-D bodies with the limited-slip option(posi) did use the same T155/80D16 tire. All other cars using a 16" donut used a smaller T145/80D16 tire. Another source for a 16" donut is the 82-05 2WD S-10 and S-Blazer with limited-slip and again it uses the smaller T145 tire. All F-bodies use a 15" donut. I'm not sure about the aluminum donut used on the 1LE/B4C F-body. Hopefully I didn't confuse you to much.
