Here it is.

Paul,  This looks very good.  Thanks for the fast work.  re tubing
sizes.  The lower outside tube O.D?   Is the rest of it .750 x .049?

  Is the oil cooler also on the right side mounted with the
radiator?  Will louvers be required on the right side cowl?  I would
love to see that detail portrayed.  Do you anticipate clamping (vs
welding) brackets to the motor mount tubes to hang  the radiator? I
have come up with a neat way to do this using split tubing and hose
clamps.   The right side cowl nostril is the source of air for the
radiators.  Is the stock opening big enough?   Can you show the
intake plenum?  Tim is there anything else you need to see?   I am
hoping James can build the cowl/ intake plenum and louvers.

Would not hurt to use one inch on all lower tubes.

To be clear:   One inch on the bottom 4 tubes and 3/4 inch on the  rest?    Jerry
