I have a 68 Camaro RSSS with a 396/325 and manual transmission. I am trying to figure out what dipstick I need. I have heard that it should have a yellow tip, but I need to know what the length should be. Does anyone know the answer or know where I can find this information? The reason I ask is because I have two dipsticks, both have a yellow tip, but they are different lengths. I think that maybe someone switched tips on one of these. I need to know which one is right. Thanks!
