Modification of Aft Spar Attach Doubler Part # KPWI0671

Has anyone modified the Aft Spar Attach Doubler to mimic the new one that is now with the kits? I have one of the early kits and noticed that the Aft Spar Attach doubler has several more holes in it than the original. I did talk to Randy and he thought they had published a drawing to allow those of us that were early to modify ours to mimic the new design ie drill more holes. I have not been able to find their drawing or any other information related to this topic, thus my posting. I have sent followup Emails etc to RANs and I have not received any reply, so I am reaching out to my fellow builders for information, or maybe someone else in the RANs office can help me.

Thanks in advance for your help.
