Me and my dad both have f-150s. Mine is an 04 and his is an 07. They boh have the 4.6L. His belt has started to squeak so he wanted a new belt and i told him about gaterbacks. He wanted one so i ordered two of them. I went to Summit and drilled down there the selections and got the same part number for both trucks GTR-4060840 it is a 84 IN and 6 RIB BELT. Is this the correct belt for our trucks? I know the 06+ 4.6's have a different intake than the 04 and 05's. Just wanting to double check. Thanks.
