Unifence body

[Brad Stoppenhagen]

I just received a Delta X5 Unisaw from an employee. It has the newer Unifence rails (silver), but is missing the fence body https://www.ereplacementparts.com/fence-body-p-83947.html. I see that the newer version has larger black screws on the front of the body, while the older one has smaller screws. Are both bodies interchangeable?

Out of curiosity are there other brands that would work with the unifence rails, or would I need a whole new setup?
