    Great, yes #19 it is, thanks for the lead. There is an early type and a late type. The springs to rebuild the late type are available, but i'm struggling on the early one that I have.

    Hi,
    a brief update.
    I contacted vibrachoc, who were very helpful. Unfortunately they could not find a match in their system. They can possibly supply replacement springs if i can provide the relevant properties. So, back to 2 questions - anyone know the free length, and the load supported and/or material properties?
    Regardless I'll update again once the issue is solved, for the record!
    Cheers,
    Mathew

    I have these on my Bora. When one drives around WO the interior hatch cover you can see the engine moving and at times bobbing up and down. The rear is secured via a cross bar mount isolated by a rubber bushing to the transaxel.

    On my Espada the engine mounts are rubber and the transmission mounts are the spring vibrachoc type.
    Consequently the shift stick bobbles up and down on some roads, it's a bit odd ...

    One Espada owner has managed to cast urethane into that Vibrachoc assembly to dampen any oscillation effects.

    Hi all - a quick update to close(?) this out, and possibly for future reference for others.
    I've come to the conclusion that my mounts are okay. When i first looked at the one side it appeared that the spring had collapsed. Since, with the car up on stands, it's evident that both mount springs are symmetrical, and that the spring has compressed under the static weight of the engine equally on both sides. This allows the engine to oscillate, or at least move up and down. See photo attached. I didn't remove a spring to measure it, but in place came u with the following approximate dimensions, for what it's worth. Remembering that this is the early type spring.
    Free length - could not measure, but in situ approximately 50mm, plus the spare length at the end, say another 10 to 15 mm.
    OD 2" or around 51mm
    spring coil diameter - difficult to measure in place, around 8 to 9mm
    Resultant ID circa 34mm
    May your engines run smoothly!
