This summer I replace the axles on both trailers. The
1954 Liner had new spring axles when we picked it up in 2005 in Florida and the 1979 Safari had the original torsion axles. Uwe at Area 63 Productions installed new torsion axles and 12" disc brakes on the Liner, since that involved removing the springs and welding new plates for the torsion axles.
My son and friends replaced the axles on the Safari and installed the new 12" disc brakes. Uwe completed the brake lines and actuator installation.
You can see the that the new axles raised the Safari up about 1 1/2". It was necessary to jack the Safari up in order to reinstall the wheel after the new axles were installed.
The axles had the low profile brackets and all four holes on both axles had to be redrilled to fit. Not a bolt in experience.
Here are a few pictures of the process and a comparison of the 10" brakes from the Liner to the 12" brakes on the Safari.
