Thanks Mike
I removed the fans from the B unit this evening.
I drilled them out from the inside, starting with the small bit in the twist drill and working my way up to a 7/16 bit. I enlarged the holes one size up at a time, using my miniature drill press until the bits got too large. Then I continued to increase the hole, until the final size.
As you can see the new fans drop right into the hole. I've started to drill out the fans in the A unit, that should be done shortly.
