    Think the mount strap was bent out of shape, nipped it up and it’s sorted.

    Wonder if you guys could help with a couple more quick noob fixes.

    1. In the rear axle image below, is that the correct order for those items?

    2. Is that the wrong replacement link for the chain right? What spec do I need?

    Stepped spacer goes on the left for drum back plate to bearing and longer spacer goes in the right for speedo drive and the thin nut and a washer you don't have holds the speedo dive on with big nut on outside, 530/5/8th is rear chain size.

    Stepped spacer sits inside the frame or inside the drum brake?

    I do have the large washer but I think I’m missing the Speedo drive altogether!

    The stepped spacer goes between the back plate and wheel bearing inside of hub and the spacer nut goes on the outside of the back plate between brake back plate and swing arm.

    Ok! I have no speedo drive at the rear hub / axle - does that change things? The cable from the speedometer disappears inside the gearbox from underneath. I’m not sure it ever worked though.

    That said, is everything now correct in the photos? I assume the outermost nuts should sit outside the swingarm and everything else sits inside it?

    That's correct, if your speedo cable goes to the gear box its a 63-65 gearbox middle cover as 66 and later bikes had the speedo drive on the rear wheel. That is a 66 and later wheel as the early bikes never had the extra speedo drive on the hub as they used a different dust cover and spacer, below is a pic of my TT with no speedo drive. You could either fit a speedo drive and use the wheel you have, find the correct hub and spacers or make a dust cover for the wheel you have and a washer of the correct thickness as that would work ok.

    Thanks! Yeh this bike is a bit of a mutt - the V5 says it’s a ‘63. I think you pointed out before it has a ‘68 front end in the past.

    Should I retrofit the wheel based speedo? Is it better?

    Your cheapest and best option is to fit a speedo drive to the rear wheel with the correct longer cable.

    Ace. I’ll order that up. I’ll need:

    1 x Speedo drive
    1 x long cable
    1 x large axle washer (retain speedo drive)

    And finally (sorry) on the left side the swingarm sits like so?

    Correct, don't forget an adjuster goes on each side as well as in my pics :)
