Right gaskets/washers for differentials?

Stopped by the local Toyota dealer and got the crush gasket set for F/R differentials. Are those the right ones? I remember seeing some pictures posted here of taconians changing the diff juices and the gaskets looks different.

 

Looks right.
2 more for tcase.

 

Thanks.
My truck doesn't have a T-case . Transfer is done by telepathy. Is a PRO!

 

And tcase oil at 55.00 a liter

 

Are new differential drain/fill plug washers really needed? I've reused mine on Toyota pickups dating back to a 1974 I still own and none of them ever leaked or seeped even with Mobil 1 synthetic gear oil. Ditto in regard to Toyota automatic transmission oil pan drain plugs.

 

Don't know if is needed but $7 for gaskets is nothing next to $196 spent on oils for engine and diffs F/R. I know what I'll will be doing Saturday...
