    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:

    Right! Finally finished refurbing mine.

    Got some stainless pins machined up.

    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 ???

    Re: clamshell catches

    Dunno why I went all black - just prefer the look to be honest.

    If it falls off after a while I'll redo it or maybe remove it an polish it. As they are all fitted with e-clips I can take them apart very easily.

    Springs were crazy money for just 4. If I wanted to by a few hundred they would have been much, much cheaper per unit.

    Pins I have made by a friend but as you say, making batches of them would be pretty cost effective. The only problem is that each catch seems to be a slightly different size. I don't think fiat were too bothered about tolerances when they have them made! I had to do a bit of filing of parts to try and get them all the the correct sizes to work with the pins.

    Re: clamshell catches

    Wow - they look the business ! I'll have to think about how I can smarten mine up . I haven't looked at them yet. I dont have the contacts to machine the pins so will be using the book binding pins (chicago screws ) recommended in one of the other threads.

    Re: clamshell catches

    What tool(s) did you use to remove the excess material, including the post?

    The originals are just polished? I see the reasoning that powder coat probably would just fall off eventually. Any experience from those that did powder coat?
    I just grind and then polish with sanding paper? Wet sanding?

    I think I'll opt to keep the post under the handle, even if the originals didn't have them. To stop the handle from bottoming out to the glassfiber. But maybe not an issue with the thick rubber used when mounting?

    Where did you source the rubber? Could it be an idea to use thin rubber and have parts 3D-printed after taking measurements on the car, to go between the rubber and the catch? So that the two parts level up correctly. It seems one needs to use different thicknesses for the two parts?

    I was fortunate to be able to use machines at work.

    https://app.photobucket.com/u/karnev...8-a3f54c3cfaef

    I cut the excess material off with a slitting disc on a hand grinder first then machined them to size on a miller.

    I think I am right in saying that they are hard anodised.

    My next step is to get them grit blasted and powder coated.

    I am building a Lister Bell and I believe the spacers to be part of the kit.
    Is it worth approaching them to see if they could sell you a set?

    Re: clamshell catches

    Thanks!
    A friend of mine owns a workshop and most probably have all the machinery.
    I was pondering asking him. I'll probably shave off the larger chunks and ask him to do the finer bits.

    Ok, yes - I was thinking maybe they were anodized. Yours are? What level of surface finish do you need before anodizing?

    Yes, maybe I could ask LB for that.
