I have sold alot of Sharktooth grilles. I'm 54 and bought and stripped alot of dusters darts and demons in my time. I thought I would let you guys know that a 71 340 grille is on its own and is different than 71 twister and all 72 grilles. My car has a original untouched 71 340 grille notice the fins are silver I did not paint them and had this grille since 1977. The grille is molded in black and painted silver. 71 twisters are molded in gray and the fins are blacked out. 72 twisters and 340 cars have the same grille as a 71 twister. Did you ever notice that some of these grilles go for a high amount on ebay. They are usually 71 340's and the buyers know it. The gray grilles are usually cracked above the and or below the parking light lenses. The molded black 71 340 grilles are alot stronger material and are never cracked. My 71 340 grilles sold for double the amount of twister and all 72. I have five 72 grilles left hanging on the wall all are cracked where mentioned. 71 grilles are also stonger where the pigtails go in. I had alot of twister a 72 340's broke out. The repo grilles are junk. They are resin and like all resin models they droop or sag when in the sun. The repo wings are the same way. They will sag in the middle make a prop for yours at a show. From the factory they are arched. FYI Steve
