if you have not done it yet .i did mine last week.
when the sump is dangling down you will see thin rubber gasket on sump.this fits onto a tray that goes all the way across the sump, above oil pick up pipe.ease this off carefully it goes all around sump.when this comes off the sump will drop off leaving the tray fixed to the engine.hope this helps.it took me half a day to find out and ten minutes to remove sump after.chicksfan calls it a spacer,that`s what threw me.
