Cool, I like the DIY approach.
I run the Slee t-case skid which has a bracket that goes up to the frame & gets U-bolted in place. Also have you see the IPOR skidplate? That one is serious, replaces the crossmember.. would take a bunch of work but I suspect you could fab up something similar if you had the time. But you better regear before bolting that thing on, it's heavy
