50 AD truck - M2 - Wheels 'bow' out?

[Mgicm]

Looked at a 50 chevy pickup half ton. Has a M2 front end and 20 inch wheels all around. Guy drove it and when he makes either left or right turn, the wheels look very odd like the tops stick out on an angle as compared to the bottom of the wheel. Ill try to get a video but it looks scary. Almost like the wheel pushes out from the top on an angle out and will come off lol.

When parked and the wheel turned, the whole front end of the truck height changes oddly as well. Just looks bizarre. Never had any experience with M2 front end.

Any ideas on this? Is it in need of a whole new front end or is it more camber/alignment?

thanks GP.
