A/C cars also use a longer dipstick than non A/C cars because of the added length of the extra upper tube extension. So if you don't have the extra tube you need that and the longer A/C dipstick to make it correct. With the A/C compressor in place it's impossible to check the oil as you can't reach the dipstick handle of a non A/C unit. I don't have a picture, this is just from memory of working on many Pontiacs through the years, hope it may be of some help to you.

Thanks, I knew I wasn't going crazy!
