Does one of the brackets mount to the front of the pump, behinde the pully, if so, did you go through the pully and loosen those bolts? I'm not familiar with jeeps in perticular, but some setups are this way. You can go to your parts store and look at a new one to get some ideas if you just can't figure it out. There is probably just one bolt that you couldn't see. Get a small merror or use your wifes compact if you have to. There may be a tensioner pully that you might have missed also.
