Ever had a night mare jump up at you?
I recognise this latch... With out the steel reinforcement plate covering the soft cast aluminum.. It was in the late 80's when I purchased an after market hard top for a CJ5 jeep. Those looked like these but with out the steel plate over the top. With out the steel plate, they will plain and simple break out around the latch pins. I Tig welded mine and added the steel backer to them as well.
Good luck, my jeep top was made by Acme. No idea if they are still around. Maybe they are OK with the steel backing plate.
