I have my tail mounted and about to install rudder hopefully for the last time. I ran a plum bob through all hinge holes. And top and middle are centered. Bottom is not centered. I adjusted the rod end two turns in on bottom to make it fit. Seems to not bind but I haven?t tightened the bolts yet. Any suggestions? This is for a rv-7a and I cut 5/8 inch off the front spar
