    On Jeff's diagram, the hole you have to add seems to be in the position of the post. On Andy's the hole is higher and the post is still there.
    Interesting that the Stratos has the three holes on the other part. Might do that to mine, not sure though.
    Ah!, I see what you mean now. I think I'd do it like Andy has and leave the cone shaped 'post' as it is.
    You'd have to lift that part of the catch on an original car to see how it should be. It never shows on photos. It's always covered by the spring loaded black part.
    The third hole has already been discussed earlier in the thread. I think I would have the third fixing. It's original spec.

    Cheers guys. What does the post do if it can be kept or removed?

    It limits the 'parked' position of the black part (the part that you grab to open and close the catch).
    Otherwise that part would bottom out on the bodywork.
    On the round arch car I had, that black part of the catch was also reduced in overall size slightly, to stop the end bottoming out on the paintwork.
    I think that might just be a round arch 'thing'. 'Not required on square arch and Stradale?

    Yeah, just wondered why it could be removed without it affecting stuff. I might remove mine and put the second hole in that place. If I use a cap head fastener in that hole it will recreate a stop if needed. If not I'll put a countersunk fastener in it.

    I can see why the lever might catch on a round arch car, because of the profile.

    On my car's round arch the catches are spaced off the body work. Not sure if this is standard but they have 3 countersunk screws, and the spacers are not that obvious...

    Re: clamshell catches

    Picked up another catch - arrived in the post today. No post. It's not been removed - it was never there!

    To confirm, the spacers are noted in the Transformer build manual.....

    Yes, they're always rubber mounted.

    I'm fairly sure the originals didn't have the 'post'. Here's an original:

    And the result:





    I'll be drilling the second hole in the fixing plate when I come to fit - and will be using a cap head to act the 'post' that acts as a stop. See discussion in previous posts above about this.

    Re: clamshell catches

    Hello Leigh
    Very neat refurbishing work ; congrats !!!!

    This is a sample of parts ( spring and pins ) that could be done in "economica" batches by the Club ......
    Beside the fact those Overcenter catches are become avery rare item to find !!!!!!!


    Just a small question ;
    why did you coated black the alu bracket and not aslight polisch ? apart it's not "in period" LOL there is the risk of damaging quickly the coat edge on the top when you clamp them frequently ???
