So here is a pic of the inlets...and below is answer I received from Yoder.
Yes! You can purchase them they us. They are $29.95/ea. and require a 39/64 hole. Since that size is pretty specific (and, perhaps, a bit hard to find for a drill bit), you could try a 5/8" hole which would be 1/64 too large, but, would most likely work.
