I then made 'cartridges' for the diffs, these were milled out of plastic. The square end blocks with the hole for the diff input stays intact and serves as a stop for the two side pieces when installing the diff. I am using 10-32 blind nuts in the side pieces, because the end chassis holes will also be bumper mounts. Those will take far more torque than the 1/8" aluminum tapped out, and are replaceable. Bumpers have yet to be made, too many ideas and I can't settle on one, kinda frustrating!
