Paul,  re the drawing you just published (not for the first time), we
may be at a place where I can install mounting brackets as a part of
the Universal Engine mount,  You would have to come up with a
specific radiator and oil cooler and all the mounting details.
Include the louvers with all mechanical details.  I'm having fun
now. The X could make a proper foundation for a frame.   Jerry

I hesitate to do that. Most people want to make their own decisions
on rads. However if you plan on a fire wall forward standard
configuration then that might be another matter. I like
Howe rads as they are all welded and correctly priced.
Summit racing. They also need to be modified to two pass.

Think about it.  There will never be a better time to mount the
radiators  than when the engine mount is still attached to the
fixture in my shop, not yet painted and  with the needed tools at
hand.      Jerry

Do you have any customers for the complete system?
