Ah, gotcha. You're talking about the plastic piece that holds the front of the center diff in place, right? Yeah, that would be great if someone made an aluminum piece.
Would any of you guys be interested in something like that? Since there is no manufacturer that makes one, I could see if the guy I use for custom CNC work would be interested in making a few. I can do the design work in SolidWorks then send it to him to get a quote. He's done a lot of work for me. I designed, and he machined, the front and rear brake caliper brackets for my race car (we went through several iterations of the front design too), he's done a bunch of brackets and plates for me, and he machined the hats on my front rotors to convert them to floating rotors. He does quality work.
I would think we could do the piece out of 6061, or maybe even 2024 aluminum.
