1997 Mercury Grand Marquis - Steering wheel

The leather on the steering is starting to tear and I want to replace it with an identical color match one from the auto recyclers. Will it make a difference if one is from an "LS" versus "GS"?

I found this link:http://www.pontiacperformance.net/TechArticles/CV_Wheel_Replacement.html, but I am wondering if the same principles apply to the 97's?

Any and all help would be appreciated and thank you in advance!

The same procedure will work.
