With the help of a friend, I removed the fuselage stands and lowered the fuselage onto the floor mounts. I did this because the next tasks will involve a lot of climbing into the fuselage.
First, I inserted the aft cockpit floorboards and the wooden work-floors, then mounted the elevator bellcrank. I plan to leave it permanently installed from this point forward, since I won't be painting the inside of the skins back there.
Next, I re-installed the control column, then installed the front and rear control sticks. I had to ream out the brass bushings to 1/4" for a good slip-fit with the long AN3 bolts that attach the sticks. Next, I mounted the forward elevator pushrod -- the one that interconnects the sticks. Once it was connected, I just had to play with the controls for a bit. Fun!
One you install the sticks, it becomes clear that you'll have to trim quite a bit from the front stick length in order to clear the instrument panel. In my case, I'll have to check the clearance with my Infinity stick grips, as they're pretty tall.
