This started as a kmiata NB ppf delete. I pulled the threads out of the original setup and wrecked a few differential housings.

That got cost prohibitive so I had a new mount cut out of 7075.

I'd like to get 300 bucks out of this unit that won't have you break a bunch of differential housings. If you happen to have the 6061 mount and want to run big tires I have an additional 7075 mount I had cut I would let go of for 100 bucks. Yes, i know they are new for 299. To that I would say price 7075 and machine time.
