Apparently, Chrysler produced different, two to be exact.
For passenger cars they used a -15F from 62-68 and a -20F for 69-73. My 68 along with another 68 core support has a -20 on it.
So, we seem to have some difference between trucks and passenger cars. The earlier one also is printed "-15F with Mopar Antifreeze" and the late one is printed "-20F with Chrysler Antifreeze".
Looking for some input, to find out when the transition was made and what some of your trucks have on them. Also, curious if they used these decals on the WM300's. I have a picture posted of the two different decals at the link.
Thanks
