Have found that the diff does not want to come away from the sump

The diff still has part of the drive shalf attached, do you think that if l can get the end of the drive shalf out then the diff might come away from the sump

Also it a R&D diff but im sure that make no diffrence because it just pushed on when l fitted it a year or so ago

Also the sump is not attached to the block either now

So any tips would be welcomed

Cheers
