How do I remove the sump of a 1.3l Rocam engine of a 2003 Ford Bantam bakkie?

I don't want to remove the engine from the car unless I have to, but will do so if its the easier way of getting the sump off. Quite apart from that, I ESPECIALLY don't want to disconnect the inlet- & outlet pipes from the aircon compressor - but again, I will if I must. The difficulty is that the bracket holding the aircon compressor (and the alternator, which I have removed) hides one or perhaps two of the sump mounting bolts. As the aircon pipes are not flexible, I think that I MUST remove them (and, unfortunately, decompress the aircon system in the process) in order to be able to remove the bracket holding the aircon compressor. Difficulty #2 is that I have not, so far, been able to source a copy of a Haynes or similar Repair Manual for this car.
