Installing Inner Fenders, Hopefully

[buckaneer]

Hi
This is my first truck project. I bought a 62 stepside and I'm putting it back together. I am about to put on the inner fenders. I have the inner fender seal that goes between the cab and inner fender. I also have a pack of inner fender mounting grommets. It's a pack of 4. Should I place them between the cab and inner fender, the inner fender and radiator support or both? I bought these from classicparts.com. The description they give says "4 pc. set does both fenders." Am I correct that I need a pack of 4 for each fender?

Thanks
Buck
