a little bit of a upload
been to a local driveshaft place that also shares my second name haha

talked to them about a uprated prop shaft for all 340s, my specs were 500nm torque limit, 2 piece, bolt on and they said yer sure when you want it bascilly
i took a spare prop with me to show them and some pictures that i fount of uprated props,
before they give me a full quote they want to see the ends that were inside the prop the metal bits you clamp down i did take pictures of them but they wasnt as good as seeing it in real life
so i will need to cut up a perfectly good prop
they then said for a prop
with out the special adaptors would be around £240
that would then be plus the adapters taking it to around 300 for a guess
so you would just slide the adaptors onto the drive line then bolt up with prop like a normal car so you wouldnt have to take the slider of to remove the prop = less wear on the splines
i thought that was a decent price regards the spec only thing is you would have to weld a support for the centre bearing not much of a biggey but added complications
i hope that lot makes sense
