I'm trying to buy a front grill for my 93 GMC C1500 Sierra SLE and apparently the grills are different depending on what motor you have? I would have thought that the double headlight grill would be all the same irregardless of engine type? Apparently the grill that fits the 305 will not fit the 4.3 V6 0r the 6.5 diesel? What gives? Arent they all the same as long as its a C1500?
