5.9 Magnum AC pump adapter
So, it looks like it will work fine if I drill a counterbore in the bottom of the bolt hole to clear the raised lip around the bolt hole on the pump. I'm not going to, however, since I want to send it back and get the same thing with rear exits rater than top exits to clean up the plumbing a little better. I saw a universal swiveling on on eBay that may work better for less money.
