Whats involved in doing this? Do I need to get a new gasket since Im assuming I have to take the cover off to drain it. Does it have a fill plug to fill it back up?

How much fluid and what type/brand/weight should I use?

http://bullittarchive.com/1005.htm will help you out.

You'll need to buy some RTV to make your own gasket

Would the dealer have the gear oil and friction modifier?

Does it matter which gasket maker you use?

Of course the dealer will have it. Use blue or black RTV for gasket.

You lose Killy you don't need to use a gasket.All you need is black
RTV.Also Royal Purple is one of the best differential oil you can use
and it is proven to work very we'll and millions of people use it and like it.
Useing Royal Purple you don't need friction modifier it already has it in it
so, on need to waste ten dollars for nothing.

It says to use that FOR the gasket so you lose for attempting to correct someone when they weren't wrong

Royal purple is great, but not required by any means as the FMC will be fine

No need for the gasket you are wasteing your time and money
and all the need is black RTV.Useing Royal Purple it cuts out the need
for friction modifier so,if anyone should be shruging it should be you.

I guess I could word it in another way so you'd understand what I believe Kilgore and I are trying to say.

The Black (or blue) RTV will act as the gasket. I'm not telling him to go out and buy a gasket

+1 extra
