I bought these canopy guide blocks long ago and am now getting to install them. They help keep the aft end of the canopy centered as it is lowered. This will, hopefully, be effective at preventing broken aft corners of the canopy as others have encountered.

I also took time to scuff off all the surface corrosion from the roll bar. I had neglected this for too long and had to pay for it with added elbow grease. After several hours of scrubbing, the surfaces of the roll bar are nice and clean and ready for priming.
