The 1987 through 1993 Z28 gears had the two letter code "WS" ink stamped on the aluminum side cover or the aluminum end plug. It had a fast ratio (12.7:1) and had a travel of 70 degrees lock to lock.
I don't know if your rally sport suspension was a FE2 or Level 1. The FE2 or Level 1 gear was also a fast ratio but it had a slightly restricted travel of 64 degrees. It was identified with the letter code "XH".
The base Camaro gear a slower ratio 14:1 gear with the same travel as the Z28. It was "JL".
So the worst case would be that you would have an additional 3 degrees of travel in each direction. With today's wider tires, this could possibly cause some minor tire rub at full lock.
