My CK25AR didn’t have both holes pre drilled.

At least least my translation of the manual the ball studs I originally put on the knuckles were too tall to clear the wheel in the rear position. I found some random lower studs in my personal box and got it solved.

Drill out the forward hole and give it a try though. You have to slide the rack around and change link length to get the toe and ackerman to where it should be. It’s not a terrible thing to learn the feel of for your set up memory bank. Very aggressive.
