MECUM DART?

To build a clone today, what choices do I have for a radiator besides finding an original and having it recored ???
Or if I was just a building a nice 68 with a hemi crossram and not worrying about radiator numbers, are there other 68 BB style radiators that would fit and work ?
I’d like to know what’s in that yellow car,
any idea ???

I was sneaky enough to pick the rad from my ´68 SB Formula S, before it went. Looks identical exept for #031 instead of 033, the BB rad has. But guess it is not easy to find one out of a 340 car either.
Think there are even alu rads with a nice OM style top can if you look around.
