I never asked what is the best seal to use. I asked how to install the seal. Pay attention to the question being asked before just responding with a brand name. Thank you all for your input the seal i used may not be the seal of your choice but it is my truck and i will repair it with what i am able to when needed. My truck is my daily driver and i usually do not have the time to wait for replacement parts to be ordered and shipped. As i stated above i will look into the Best Gasket company for future repairs. The seal is in it is not leaking case closed. Please delete this thread and lets move on.
