Trans Am GTA 89 limited diff. cover

Hi,

I ve a Trans Am GTA V8 5.7 TPI from 1989.
My limited diff is leaking oil..

this diff. is still orginal, its time to reseal it with a new gasket...
Does anyone know a site where i can get it ?

What's type of diff do i have ?
I counted 9-bolts... what's part number of the gasket ?

Then ONE important question, how much OIL should i fill in this diff ??
till the plastic plug ?

Thanks for your help !

Just use the kind of gasket that come in a tube.

Yes, fill until it reaches the fill plug. Should take about 2 quarts or maybe slightly more.

I dissagree, go to atuozone or checkers and buy a gasket. Their like 7 bucks and then use some blue rtv to help it out. And it take about 1 1/2 quarts. Look at it this way..if gm used a gasket then so should you.
