LT-1 Spark plug wires

My new set of plug wires showed up today. Ordered them from

Couldn't be happier, they are very well made, fit perfectly and all the wires are numbered already.

I know other owners with the LT-1 have struggled either locating these or coughing up the big bucks to pay for them. These can be had for around $119 shipped to your door! Part numbers are 556010A and 556010B (order both)
