Default Canopy Latch - Supertracks

I had the Supertracks Canopy Track Extension laying around for over a year now. My prop is removed for an overhaul so I thought this is a good time to do the installation.
It all went smooth however I´m missing a canopy latch to hold the canopy open a few inches during warm weather taxi, the one I had cannot be reused with the track extensions.
So I came up with two solutions, here is the one I finally realized:

I reamed the WD-644 canopy roller just a bit for a smooth inner hole. I then fabricated an aluminum slider which goes inside the canopy frame and is springloaded. It is hold in place with the AN525 screw and can slide a litle more than 1/8 of an inch. The slider is held in the up position with a springloaded round handle which locks itself in a small cutout in the canopy frame. Pulling the handle out a bit lets the slider pushed down by it´s spring and a locking pin locks the canopy in a drilled hole to the C-657 Canopy Roller Track. The locking pin is actually a set screw and can be adjusted with an Allen key from the inside.
The original canopy lock
All the parts required

This is how it looks like installed
