As far as I know the 300 has the same bolt pattern as a 208 or 241 so adapters shouldn't be an issue, but they have 23 spline inputs vs the 27 spline. So what are the options? Anyone make new input gears for the 300? I'm sure someone could get 23 spline output for the 700R4 but transfer case gear change would be a nicer option. This is for a Jeeper friend, hes weighing going with a 700R4-205 or 700R4-300 combos. I am pushing towards the 300, I just like the cases, the gearing options and upgrades for them make them decent cases I think.
