Since your post clarifies that it's actually an 80, that you want to swap a complete 81 rear into, then yes, as others have said, this swap will work.
80-82 rears are all identical, and completely different from 79 and earlier rears. Though all 78-82 Corvettes, equipped with steel springs, use the same 2 1/2" wide spring. 77 and earlier springs are 2 1/4" wide.
Have I completely confused you now?
