If you get the metric ones it's straightforward enough to drill the holes larger to take the imperial pins.

obviously remove the gear lever too, but yes, it really is much easier to take both out together.

Not sure I see the point in fitting a more powerful engine if you aren't going to use it though, a standard GT6 is no slouch after all 😃

My shaft is being sent away for materials analysis, it will be interesting to see what they find.

My car has a swing spring Pete.

I have seen a Stag CV shaft that has sheared in the same manner as my car’s modern UJ shaft.

Having previously rejected two sets of CDD CV shafts for my TR6, I elected for their uprated UJ shafts on the GT6. I have sent pics & a video showing the bearing hasn't seized to CDD, will see how they respond.

Mine was a 4 week recovery Steve, Euro breakdown cover isn't always very good.

Here's what happened to my car:

Not difficult to remove a GT6 gearbox from inside the car with the engine still in place, remove the passenger seat and remove via that footwell.

I realise that this thread is five years old, however, I thought it very relevant to a recent experience I have had in my Mk1 GT6. Having heard of issues with shafts shearing and with my car putting out a fair bit more power than standard, I decided to fit a pair of CDD shafts. It is worth noting that the spec' of these shafts isn't the same as that on this thread, CDD are now using EN24 but the hardness process isn't listed. My shafts have been on the car for a couple of years and have less than 8k miles on them. My shaft sheared in France and it took four weeks for the car to be repatriated, I have collected the broken shaft from the garage sorting the issues out for me, the bearing is free, there is no sign of blueing on the shaft, it has sheared a couple of mm from the inner end of the woodruff key slot.

How has this progressed in the last year?

Alasdair Southall's customer service is exemplary, I had bought my shafts from Rimmers, when I had the issues I contacted Alasdair & Rimmers via email, who do you think responded first?

I went with CDD's uprated standard shafts.
