Channel MASTER 6346 3m SMC dish

Hi !
Just an information
after a lot of time I found the original polarmount of 6346 dish.
At the moment I use Proform h-180 motor , but it's' not enough for the antenna in KU, so I am going to install original POlarmount:
the question is:
I see there are only three declination set-up, for use in KU band I'm afraid not so good:
any idea?
Someone who use this antenna know about it?
many thanks
