Anyone know about the outside diameter of the PCA connectors?

I thought I remember reading that Outlaw was going to have to OD made slightly smaller so they don't interfere with one another on the back of the 950. The PCA 1.2's were supposed to be the smaller dia and new batches of the .5's and 1.8's were also going to be smaller.

Is this true and how do you know which .5's or 1.8's you are getting?

Thanks.
