antifreeze decal

I have a 67 a-body . I ordered the underhood antifreeze decal from Year One. The decal they sent me is wider than the original one that was on the car. The new one is too wide for the core support. Year One said this is the only one they offer for my 67. Has anyone had this problem before? who else would have the right decal?

Thanks for the help Jim


Is this the one you are referring to?
