Hi guys...just purchased a nice 79 z, googling some piks i notice that some 79's have a grille emblem and some do not. mine has the std vinly z28 emblem on the front facia...but im speaking of the center of the grill. I believe its the same emblem that is on the rear gas tank door? mine has nothing but yet ive seen cars online with and without. any ryhme or reason for this ? also i notice there is chrome trim on the windshield end of the hood...and two lil pieces that match i believe on the front fenders....my car doesnt have that....i would think it should have it to match the chrome drip rails above the side glass. although my front and rear glass trim is painted flat black. any info would be appreciated...thanks alot.
