VFD and Air cooled spindle

I am buying a VFD spindle from automationtechnologiesinc.com (this one specifically: 800W (1HP) Air Cooled CNC Milling Spindle, KL-800A |). It says its 65mm OD, as I’ve seen that’s what’s recommended, but its not clear if my existing mount will work, or if I need the new dewalt 611 mount. I have the 24v spindle that came with whole kit that I got about 5 months ago - before they discontinued that spindle and started recommending the dewalt 611.

Will that original spindle mount work with the 65mm VFD?
