new spark plug wires

[kirkfeere]

hey,

I opened my hood and saw a small spark comming from one of the spark plug wires while my truck was running.

i called to get some new wires and they asked which leads i need. 10.5 or 9.2 , I cant seem to find the serial number on the coils. theres a small bat code on one coil on each side could that be where the number will be.

I asked my buddy about the difference from the 9.2 and 10.5 and he says the length of wire is this true, does it make a big difference between each set of wires

Yes it's true. Measure your wires and get the same lenght. I"m not sure it would make any difference,but I would get the same. The number I beleive is on the bar code. Try AC Delco site that should help
