Drilled the #11 hole for the GSA 28 servo connecting rod end bearing, and assembled the GSA 28, new brackets and the elevator bell crank.
Dang... of course if there are two ways orient something that seems symmetrical, and only one will work, I will usually find out after trying the other...
As is the case with the bell crank, the shop side of the rivets holding the two halves of the bell crank interferes with the forward AN3 bolt for the GSA 28. I should have dilled the #11 hole .40 inches off the other side of the half mark.... that way the universal side of the rivet would clear.
Looks like I'll have a perfectly symmetrical bell crank having #11 holes .40 inches from the center line.
