I am installing the Bleed and Feed system on my 08 Deluxe, and need to mount the compressor to the bottom of the tranny case. I see that there are two holes at the bottom of the case that are already threaded.

Anyone know what the thread is, and what these holes are intended for? I have read a few of you have drilled this hole larger, but don't know if this is necessary, since the threads are already there.

As always, thanks in advance for all the assistance.
