You’ll need a different mount.
There are a few options here. You can use the Inventables 611 mount with a shim of styrene or a shim of aluminum. This is what Inventables did with their 800w air cooled spindle and it is what I have done with my Makita (also 65mm).

You could also go with this spindle mount found here if you want to make it yourself:
Or if you want to order one @JohnScherer is making and selling them here:
Hope that helps some.
