Any suggestions or guidance will be greatly appreciated.

Drain diff
Pull diff cover
Support diff
Disconnect diff
Remove diff

Reverse process

Make sure you used lactate on bolts when putting it back in.

I do it with my car on jack stands, but it would be much easier if done on a lift.

What if you are lactate intolerant?

When I swapped mine out, I noticed that the front mount bushing was bad. So I went to an aftermarket derlin bushing. It was not fun getting the stock bushing out or getting the new one in. I also upgraded to the larger front bolt which required drilling and taping.
I needed an extra set of hands to get the old diff out. Had to rotate it upside down as I remember. I also dropped the gas tank and unmounted the sway bar to get to the rear mounting points. When the diff is out is a good time to also install adjustable lower control arms.
I went with a 373 with 40% lockup. His seems to work good with the tall first gear of my tko600.
