Building your own radiator support?

[Coldshot]

I'm thinking of building my own radiator support, but want to know if anyone has done it before and what the measurments are? For mounting the fenders.
I have a 6.0l LSX going in and want to fit a good sized rad in there.
Would it be best to get one and modify or build it from scratch?

I know there's other rads made for this swap but I've searched and no ones has done it, so I thought I'd ask and see what people have done or come up with.
