Ya I went to 3/4 ton K5's are 1/2 ton LOL
I have an SM465/Np205 and I used the same shaft.
You have a 1330 series yoke on yours so it will require the Napa #447
That is why you had to use a hybrid joint, the 12 bolt has a 1310 yoke and the 10 bolt has a 1330 series yoke.
I did have to drop my T-case 1.5" though as the added 2" from the 14bolt had my rear yoke binding.
I am still not happy with the driveline angle even though I have no vibes.
But a lift is sitting in the garage waiting to happen and when it goes on I will be mowing the perches off and rotating the axle.
When I did the shock mounts I lifted one side with the fork lift till the other side was just off the ground and I compressed the shock 1/2" and tacked it on then did the same to the other side and then stiched them up.
