One of the issues with the one-ton conversion is the one-ton knuckle's upper ball joint mount is 2" higher than the OEM knuckle. This causes a camber change with front end up/down motion. Some find this disconcerting, but since I don't drive my coach like a rally car I don't notice it or at least it doesn't bother me.

For those purists, here are a couple of YouTube videos of guys making their own knuckles so they can design them any way they want. The first guy has his pieces cut out by an on-line lazer cutting company. His channel called SuperfastMatt is pretty good. He uses a lot of scanning/3D technology to put a Tesla drive train into a 1950 Jaguar.

This second guy is more back-yard mechanic type. I haven't followed him, so I don't know how he came up with the downloadable files to make his. I'm sure he shows how in his earlier videos.

I'm not doing this, but just thought it was interesting how they did it. By scanning the OEM and One-ton knuckles, one could come up with a hybrid knuckle. Getting it cast and milled would likely be very expensive for one-off copies. I'm not sure at what quantity it would become economical.
