All the notchbacks between 1984-1986 got that wheel, except the '84 Indy Fiero and the '85 GT. For 1987, the wheel's design slightly evolved into something similar, but it received paddle horns on each side. In total, there are three different steering wheels put into Fieros. There's the one you have, then there is...
This style, which is in my '88 Formula and is the updated style I was speaking on. These were put in '87-'88 coupes and Formulas.

Then there is the 3-spoke 'GT' wheel, which was put in Fiero GTs and the Indy Fiero.
