Also, I noticed you were looking for some aluminum center diff mounts.... I use the Integy ones. I know most people here don't like hate Integy, but I have had no strength issues with their aluminum center diff mounts. These are meant for an OFNA Ultra LX One buggy, which has the same center diff as what you and I are using, so they do work just fine without any modifications.
Here is a link to where you can buy them -

(Integy also has grey anodized ones if you don't like the silver)
