Maybe its just because it is what I am used to but I would still rather use a kp60

You do make solid points for the superduty axle. Anything on a new diesel is beef these days.
Facebook Market place around me cheapest 60 is a ball joint ford 60 from the 90s at 800, superduty 60 for 900 and a dodge 60 for 900. Should do alright on it worst case I went for a nice mountain drive on my way home from picking the 60 up.
