Keep in mind that the kits have some standard parts, but Mancini will let you upgrade for the difference in cost...
Like the Federal Mogul freeze plug kit only comes with two oil galley plugs and all the freeze plugs, Mancini has a house brand kit that has most all of the freeze plugs and oil galley plugs....
MRE-113BR is the mancini kit that has the most plugs that I would recommend....
