I finished installing the rear slider blocks on the canopy. This is very tedious work. I had to massage the canopy frame pins so that they were in line with the axis of the aircraft. This takes a lot of time getting these brackets to fit right. Once I put the fiberglass fairings on the rear canopy I will remove the 1/16" shims between the rear guide block holder C-677 and the longeron if needed. I put these there to allow the canopy to snug down on the rear of the aircraft to get a good seal.
