Manual is correct. 80-100 is a good time. Wow. That's a great deal. Pix?

Yeah, 37 is too low to change them, unless they are rusted/corroded. Welcome to the Forum as well!

Thought so to! Rockers and wheel wells not rotted! I will try to post picks. It's a reg can long bed 7700 series. Looked at newer but a huge fan of the 97 to 03-04 style. Thanks for the info

Welcome! Definitely leave the plugs alone for at least another 40,000 or so. Especially since it can be a huge pain if not done just right.
