be aware there are two types of clam shells, the truck ones don't need mods, the car ones need the triangle raised portions ground off so they don't crack the aluminum LS adapter plates

see how in the pic these are the car style ones and how they have that horse shoe looking thing embossed, well if we were to flip them over that part would be raised not allowing them to sit flush against the aluminum LS adapters, so in that case they would have to be ground flat

the truck clam shells don't have the same design, so truck ones don't need the mod
