Hi,
Anyone got a tip on where i can get a new one piece rotor for my 1985 f250 4x4 300-6 ???

 

There is no such thing that I have ever seen. If you need new hubs you will have to get them and then buy new rotors at the store and install them on the hubs.

 

They are listed at advance auto but not available.
There is no visible seam.

 

 

 

 

I sure see a seam between rotor & hub.....
You're trying to say if you drive those wheel studs out of the hub you'll be left with "an integral rotor and hub"?

The disc doesn't "just slide off" an F250, the hub needs to be removed and the studs need to be pressed out.

There's just too much generic verbiage in those type of manuals to believe any of it.

 

Yep, there is the seam in this picture. Lay the assembly on the concrete floor and take a brass punch and big hammer and drive the 8 studs out. It will then fall apart.
