SX3 rear camber links

[Benjy1]

I have just bought the 53mm turn buckles for the rear but I am unsure what the distance should be in between the ball grippers. With the standard 60mm turn buckles it says the distance should be 41mm between turn buckles. I now want to use the middle hole on the rear hubs so bought the 53mm turn buckles but I am unsure what the measurement should be between the ball grippers please can anyone help?
