Another update: Testing and development are pretty much done. Just sourcing a few last minute things. Tooling for building the main reinforcement is good to go, just need to build the jig for the front diff brace.
I've posted a detailed write up on my website, it's in the tech articles section

Heads up: If the link gets the attention of any mods, I have yet to begin selling anything, and there is no functioning section for online orders on the site. Still aiming at getting Dylan at DS1 on-board for the vendor side of things as soon as I can get another order out for materials/bolts with which to build the first run of 10 units and a couple samples to send out to other potential vendors.
