Cheers, I'd like to put new fluid into my differential, the stuff that's currently in is just one stinky goo... Now, on rockauto it appears that the wrong gaskets are shown for my car (70 GS455), they have 12 bolt holes in the gasket while mine has only 10. Which gasket is the right one for me? I hope you can judge from the pictures... Thanks Carsten
If it is the original rear, it is a 68-70 Buick only 8.2 10 bolt. http://www.taperformance.com/proddetail.asp?prod=TA_1808-G

That is what they are giving in most of the rebuild kits these days...NO GASKETS at all just a tube of goop!
