I have been waiting for someone else to respond as I am not sure myself what is correct. My '50 Chevy COE appears to have 8 holes total, so it is odd that your set came with only 7. My hood has two holes each side of the hood, where the hood side mates with the fenders. I have thin bumpers here. Where the upper radiator shroud/panel meets the top of the grill, there are 4 holes and here I have the large thick bumpers placed. Hope this helps,
