Default Sensor, Spark Knock

Can somebody just tell me where to find the spark sensor on a 1990 L98.
I have the replacement I just need to find out where it goes, thanks.

Its located at the base of the block on the passengers side between the starter and the engine mount, mine had a heat sheald around it that I had to remove first.
Your best plan of attack is to wait until the car is cold before you change the sensor because it is fitted into the water jacket so you WILL get wet when you change it just make sure you have the new one handy to serew straight in so you dont lose too much water ( unless you are planing on changing the coolant at the same time ) .
