I think that I may go ahead and do the labor myself on this rear end replacement. Lets say I get a drum rear end from a 91 and I want to put it on a drum equipped 87. Will it bolt right up. Are there and differences that I need to be aware of at all. Are there any special tools that I need to do this with. Thanks.

1982-2000 diffs all have the same mounting positions. Internally there have been a lot of changes but the external mounting points have remained the same.

Just replace that rear body-to-axle brake hose with a new one.
