Oldsmobile/Buick Repair: how to change spark plug wires, cutlas, plug wires

Question
Hi, I need help changing my spark plug wires on my 90 cutlas ciera oldsmobile.What is the correct way to change them.Are they all different sizes? Thank you for your time!

Answer
I think the OE wires are numbered, but if you get a set from a parts house, find the longest one on the car, and replace it with the longest in the set.
Then find the shortest one on the car, and replace it with the shortest one in the set. And so on.
