Ok thanks Colin. That does sound a bit finicky, so I’ll take the drive off my spare P6 speedo and get it recalibrated by the mentioned outfit. I take it they’ve done them enough not to need specific details. Of which I have not many!

I have been considering getting a flexible coupling or having one made up, given the amount of stretch available in the auto prop, to counteract clonking and play in the diff. Having owned and driven various cars with 'Hardy couplings' in the past I am accustomed to the feel in a cruiser-type car as opposed to something more sporting that wants everything to be sharp and direct.The auto prop I used was also at full stretch and the spline was wobbly, so I fitted a 25mm Britpart prop spacer from a Land rover and closed up the prop which made the spline joint a lot tighter.
They replied:I haven't got around to extracting the speedo cable from the instrument panel and measuring six turns of a road wheel yet, which is what Speedy Cables ask you to do in order for them to recalibrate your unit.
I got my speedo calibrated by Speedy cables (the name is a bit misleading).
I got a quote for £55 for calibration plus £13 for a P6/SD1 cable and maybe £20 shipping from these guys today, having spotted them in a different thread. Half the price, and perhaps even half the time spent, sounds like a winning proposition. They’re also willing to calibrate by percentage (20 pct), since I’d prefer to have everything ready to go in in one go.Which ever way you serve it up they ain't quick.

Can anyone shed light on a good/surefire way to ensure I don't get a heavier clutch pedal with the LT77 conversion? I can add that I've got an uprated clutch kit from Clutchfix LTD that will be 10-15 pct heavier than stock, and from what I understand, using the P6 slave will make the pedal harder already?
Would that count on my four-pot conversion? .
Your 4 pot conversion doesn't have a slave cylinder. I can't see it having a heavy pedal action if the pressure plate isn't seized. As you say it shouldn't be any different to a normal 4 pot.
