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.
