(2) New ACDelco Knock Sensors part# 213-3521 / gm part# 12589867, have the pair, they sell for around $40 each. $60 shipped.
I have the GM harness for the knock sensors part# 12601822 still sealed in the bag, sells around $35. $25 shipped.
The extensions were used for about a week after my LT install until I swapped out the O2 sensors. The O2 sensor extensions are normally sold around $30 a pair, $20 shipped.
My Ebay ID is davidg301 and have perfect feedback.
If interested send me a PM.
