what ever that is on the back of the rad. its is not the correct shroud for that truck ...as for trim i like the look with the sails and the rear strip i don't care for the side trim the truck looks great without it..64? you say it has 66 badges on the fenders could have been changed or you have a 66 ,... go here and you will see the proper shroud and how low and far back the fan rides...
