Greetings all,I looked for pics of Hoods in the website and did not find what I was looking for.I Know(?)that the STOCK,STANDARD FLAT hoods on 1967-69 have to be Different somehow from year to year.Are there any pics of any/all VISUAL DIFFERENCES in each year Hoods that would tell us all EXACTLY what year hoods we had on our cars?When replacing a hood on a car we are rebuilding,any Year hood will fit ANY year car,1967-69.But if we want EXACTLY Correct hoods on our project,how do we POSITIVELY I.D. the CORRECT Hood for our year car?Date Codes somewhere?Whats the Scoop?Thanks
