I have a 1955 olsmobile super 88 sedan. Want to know if i can replace the front saddle with one that haz disc brakes and ball joints instead of kingpins.

 

If you have good welding and fabrication skills and a good frame to weld to, yes. Fat Man Fabrications is one company that comes to mind.

 

Thanks for the info. Will look into it.

 

Yes ! Fat Man Mustang II style front end is the way to go if you can.
Disk brakes, Rack and Pinion steering, coil over shocks, and lots of other big upgrades.
As I recall you can order them in different configurations depending on what youre wanting to upgrade.
