I mooched the long pair of Quick Magnet mounts From Johnhamelhv. He had used the shorter ones for the front canopy mount those were 18.86mm long.
The ones I got were the other pair from a set and were 20.86mm long.
I had spaced out the port side front mount on mine to get clearance for the main gear by 2mm so I figured these might work.
They do and they work great.
I had done a little judicious warming of the canopy before anyway but now it's about perfect.
I was able to remove the tail blade shims I was using.
So if you have a buddy with an E5 you can split a set of these and it works out great.
