Oldsmobile/Buick Repair: Replacement Spark Plug wires for 92 Buick, spark plug wires, spark plug

Question
Was wondering for my 1992 buick 3.8 Lesabre, whether I have the Delco Ignition or the Motorola? It is the 3 by 2 configuration distributor module. (I was told need different set of wires for each type. )
Also, how often should i change spark plug  wires?
Thanks

Answer
Heck, Joe,
Depends on what kind of driving you do.
I'd say about 70,000 highway miles or so, but look at them running, when it is dark, and see if you have wild sparks.
I don't know what to tell you about what type you have.
Look for a tag on the distributor.
