Mines from a 02 sc and the one i got is from a 02 na. I can't get a reading on either sticks and I just did an oil change and put in 5 liters of oil. I kinked the origonal tube so I took the one from my junk 5.3 and had to cut a couple centimeters off the lower end so it was exactly the same length. Since then I couldn't get a reading so Thats why i went to the junk yard and pulled another tube and stick. This way i can try to better bend the tube but both sticks are the same length so I know thats ok but I still have no oil reading.
