A weight comparison of the two driveshafts.
The old one weighs in at 1921g
The new one weighs in at 1504g
417g lighter! That's not bad.
If I get the other driveshaft swapped out too, that's nearly a kilo of weight saving.
Did I also mention that the new driveshaft is also very shiny!
I did a quick check of the CV joint fit over the splined shaft. I wanted to see how much tighter brand new splines were compared to the old ones.
The difference is "night and day". Absolutely no movement in them at all. I'm a happy bunny.
