If you find me someone other thain T.G. making the 6 studs I'd love to know about it. Wabfab sells them but I'm pretty sure they are the TRAIL GEAR just sold by the wabbit.
The 6 stud knuckles made by Trail Gear are not up to marlin's standards or specs, so why would I run them on my rig which runs almost all Marlin parts?? I will buy them if Marlin ever does decide to make sell them, though.
