^----- stud

 

Well Einstein what size studs there are many sizes you know not every manifold on every car is the same

 

You might have to go to auto zone ect and have them look up studs for your truck. That is about the most accurate way you are going to find out.

 

Check out the parts and service manuals above and see if you can cross the part numbers, then check your favorite part store website see if they show anything and of course just give the dealer the part number and get them there.
