The o-ring should stick out as far as the original raised section that was dremeled off. Then add a thin shim, then outdrive bearing. To seal the diff cover, some RTV silicone. I have an extra diff that I'll be trying this on. But I'll wait to actually replace it until the existing diff goes out.

A friend/coworker is coming over to my "shop" today, and we are going to modify his Slash diff in this exact fashion. If there's time we might get around to modding the diff in my Rustler but that's not so important.

Do you have a drill press Brian? I think that will make drilling the countersunk hole a lot more precise.
