What does Rod use?

The mustang 8.8 fits will little mods to the beam. A guy in America makes custom stubs to use standard axles. Ratios are plentiful. A spacer is easily machined to use the standard propshaft (the mustang diff is 19mm shorter). If you buy the right cover you can also easily install some lateral bars if that takes you fancy. And a diff mount lines up with the exisiting mount.
