High steer discussion..........

Perhaps.. I was thinking more of a slight offset in the holes themselves..

Without the original jig, exact centers are in a word, difficult..

One thing you will need to ask when buying arms:

How long of a throw from lock to lock is it?

This will dictate how long your pitman arm or ram shaft would be. I did a hydoram on mine and had to get the shaft machined because my arms are short. My throw is 5".

This will save you a big headache.
