Side draft weber manifold FS

All,

A friend has an alloy manifold with 1 3/4" weber ports (side draft) that he 
would like to sell.  He thinks it is for a 1500 motor.  Can anyone verify 
that it is?  The picture and dimensions of the head side of the ports are 
shown at the following link.

If it is of interest to someone here, I can provide a complete digital 
picture.  If it is for some other mark, I will go to that list.

Thank you,
