Decode my Diff.

ok the only numbers I can find on the the axles is front 30 close to the cover

and on the rear 350 again close to the cover.

Im wanting to replace the gaskets on both differentials, but want to make sure they are the ones that came on the 87 YJ.

You dont need gaskets just some RTV. Use the waterproof stuff. Apply it to a clean dry surface and bolt half way tight, wait a half hour and tighten fully your ready to rock.
