Rolling chassis purchased from a hot rodder twisting

[Brendan1959]

Hi Folks
I have not posted for a while.
I just bought a rolling chassis from a hot rodder who pulled the tudor body off to build his rod.
It is in Australia but the story goes it was restored in las Vegas in 2012. everything look like it was replaced at the time new bolts everywhere new chrome etc.
New cast iron drums with no wear however the new studs are welded to the flanges and not swaged to the drums, is this going to cause trouble down the track?
When I had it on the jack to look at the hubs I noticed the chassis twists very easily, video(https://www.youtube.com/watch?v=AFWyhdVBYsM) seems like a lot to me, it has a float a motor and the front and center cross member are bolted in, I cant remember what my roadster was like when the body was off?

I pulled the oil tube and its as clean as a whistle inside I think I am on a winner.
