After some wandering around on Pirate, seems STaK is out of business or in the process of being bought out. Trail worth fab is buying them or in the process of a D300 case upgrade.
In all honesty I could just make this a pass drop front axle and run an unmodified D300 but limits my resale customer base. Oh, just remembered, have a driver side hoising I the way anyway. Hmmmm. Decisions.
It makes sense to me to just make it so that you can run it unmodified if you already have a passenger side drop housing.
