26X boom groove diameter, anyone?

Hi
Does anyone know the diameter of the groove on the top of the boom, where the mainsail foot tape slides in?
Looking to buy a lazy jack system, and need certain measurements so I can order it....

Thanks in advance!

There is a detailed engineering drawing of the boom cross-section on page 469 of the original Macgregor website. You can find it in the resources section of this website.
