QUESTION: Where is the knock sensor located?

ANSWER: HI CHUCK,I WISH ALL MY QUESTIONS WERE THIS EASY. YOUR KNOCK SENSOR IS IN THE BACK SIDE OF THE ENGINE NEXT TO THE DISTRIBUTOR,ON DRIVERS SIDE ON A SLIGHT ANGLE..NOT THE EASIEST TO GET AT.
I HOPE THIS HELPS YOU. IF YOU NEED MORE HELP,DROP ME A LINE. PLEASE WHEN YOU LEAVE THIS SITE WOULD YOU RATE MY ANSWER. THANK YOU, TOM..

Thanks,  Chuck

Answer
HI CHUCK,THE ONLY THING I CAN THINK OF IS THE IGNITION WIRES FROM THE DIST CAP GO OVER IT,AND I THINK THERE MAYBE THE FUEL LINES THAT RUN ON TOP OF IT AS WELL.BUT NOT CLOSE TO IT OVER TOP SIDE. [IT IS DO-ABLE] I THINK THE LAST ONE I DID I MIGHT OF REACHED IT FROM UNDER THE TRUCK OR THROUGH THE WHEEL WELL AREA.I FORGOT SORRY !! KEEP IN MIND IT IS ON THE [BLOCK NOT THE INTAKE MANIFOLD.] AGAIN DRIVERS SIDE. I WOULD SUGGEST PICKING ONE UP AND THAT WAY YOU WILL KNOW WHAT IT LOOKS LIKE AND THE SIZE OF SCOKET OR WRENCH YOU WILL NEED. I HOPE THIS HELPS YOU,,TOM..
