I have some locking aerocatches too, also not fitted yet.
Going to make my own metal strengthening plates from some metal sheet.
Got mine from the demontweeks stand at autosport international. think they were around £50

Good call on these, I didnt know they existed so I just now bought a set (£10.49 delivered). A great idea for not only strength but they have captive nuts! Saves fiddling about with the standard nuts.
