Can I use a 72 core support with 67 clip

[WB72]

I was hoping to be able to modify the 72 core support to work with a 67 front clip. I have heard it can be done, but not sure what needs to be done to the headlight area. Do they need to go out or in, and by how much?

I am not going for original, but more of a ratty style so having welds where they are not normally doesn't bother my build.

Thanks in advance.
