Hi Adam
Many years ago i bought these Latches(Photos Attached) from ‘Pauls Jaguar’ based in America which he sold as an Upgrade/improvement to the Jaguar made Latches which in his opinion were Flimsy and subject to failing which may result in the hardtop detaching from the car which at speed could be highly dangerous. I am not certain if Pauls Jaguar are still in business but it mat worth trying to contact him should you feel these would be right for you, i still have the clamps which i purchased from him which have never been fitted as i managed to source some Jaguar original fitment Latches. I would be happy to sell these if you cant get your hands on any. The last two photos show the C-Pillar hooked end clips which i think would suit the Latches already fitted on your hardtop obviously these would need to be mechanically attached to the C-Pillar, i also have these lying around should you be interested.
Regards
Brian
