a factory assembly manual would be very useful if you plan on keeping the truck ... on the front clip [truck, but car is much the same], there's bolts at the top and bottom rear of the fenders - to the cowl at top, to brackets under the toe board and at the bottom of the cowl - and then if the bolts holding the bottom of the rad core support are removed, the whole clip can be pulled off in one piece, including the rad and grill
