Ahh, here it is. It's actually from 2003. Just goes to show you that time stands still when building an RV.
First, remove the rodend bearings before installing the pushrod. A shorter rod is easier to install. Rod still too long? Don't be afraid to flex it slightly... just aas long as you don't bend it permanently. Still won't fit? Use a unibit to make a rod-sized hole in the F707-907 bulkhead, roughly in line with the pushrod. Slid the push-rod aft, through the hole, to gain clearance, then forward into the cabin.
Now that you have it in position, it's time to bolt the pushrod and washers to the control column as shown on DWG 38. If you have already installed the column and manual aileron trim mechanisms permanently, there won't be much access. It can be difficult and frustrating to get those washers in from the top. The easier way to do it would be to remove the control column, install the washers, rodend bearing and bolt out on the bench where the cussing can so some good, then thread the pushrod into the bearing when the column is re-installed. It's a lot easier to tighten the jam.
This technique works even better with the aileron push-rods (which have the smaller, nastier 5702-75-60 washers) because it permits accurate "clocking" of the bearings on each end.
