It looks like I have finally found the fix for my trunk opening while going down the road. I found Iron head Tri-Glide trunk locks. I bought the latch assembly and installed on my Trike it seems to work great will know more for sure after riding this summer, but it appears to put a dependable lock assembly in the bike made out of metal not plastic opens and closes great with solid latching system so far i am happy. If you do get it plan on a couple of hours to install but well worth it. I originally found it on Facebook
