Brava 1.4 Sump Replacement

Hi, New to Forum, have a 1998 Brava 1.4. Very Happy with car but have experienced some problems recently. The sump has started to drip oil and on closer inspection was found to be badly corroded. I purchased a new sump and started to remove the old one today. Haynes manual says undo bolts and remove. I have undone the bolts but the sump was fouling on the exhaust down pipe. Have undone the exhaust and now it seems to be fouling on the drive shaft and subframe. The pickup pipe goes through a hole in the baffle and its a tight fit. Has anyone done this job before, can you recommend a better way cos I'm running out of ideas.

thanks,

Big J.
