they vibrate due to the wear pattern in u-joints, good new u-joints should fix that
New lift, driveline vibes. Double Cardan Rear shaft?

I've done just that. Still vibrates.
I put in OE Matsuba U-Joints, had the factory shaft balanced and trued. If anything, the original 350k slip spline is the concern now.
slip yoke can also be a problem
Have you tried the stock shaft installed with the slip yoke at the diff?

I don't think I've tried that yet. Might be worth a go.... that trick used to fix tacomas back in the day
With the slip yoke low you might at least see an improvement which could indicate worn splines

Update:
Finally got around to having the custom driveshaft checked out by a local shop. My buddy was taking his shafts in for work and was kind enough to take mine in as well.
Shop reports runout at .080"
Normal max runout is .010"
They are gonna fix it and we will see how it runs.

Reinstalled the custom shaft today after it came back from the driveline shop. It's much better than it was before. Still have a vibration between 40-55mph, however it's pretty tolerable.
I think I'll run it as is until I swap the new engine in, at which time I'll also do the engine mounts and trans mount. Then see what we get.
I'm still not convinced this driveshaft is good tho. I do have a friend locally with a buttery smooth CV shaft in one of his 80s. Might have to borrow it for diag purposes....
Anyway- thanks for all the input from everyone.

Final update.
Custom fancy double cardan shaft was never right. The drone of the vibration at 65+ never sat right with me. It was tolerable at first after its trip to the driveline shop, but was still nagging at me and my OCD.
Put in a brand new OEM toyota shaft and its as smooth as it should be. If anyone wonders, yes, I'm a dumbass and spent $1500 on custom shafts and work when I could have just put in a $500 OEM shaft and fixed it.
Anyone wanna buy a custom double cardan shaft? It massages your back as you drive!

So did you ever flip your stock rear shaft ? and did it help any? Also seeing if you are still vibration free?

I tried the original rear shaft flipped both directions, no change.
The new oem rear shaft was a big part of the fix. The last of the vibrations were all but eliminated with new engine mounts and trans mount when I put the new engine in last month. See my other thread for photos of the mounts and some explanation.
Awesome I’ll check it out. Thanks for the response. I’m in a money hole right now. Really draining haha

Well then you'll understand why my thread is called "black hole where money disappears"
I understand and just read your thread. While you are almost out of your black hole I’m in middle spinning out of control hahahWell then you'll understand why my thread is called "black hole where money disappears"
get that shaft modded (if its length allows), remove the double cardan and add a slip yoke. keep it spare

It's still around for a trail use shaft should I ever need it. But it's no good for the highway...
Who charged you $1500? I usually work with a local shop or JE Reel, Toms and Adam’s.

High Angle Driveline...
tmxmotorsports
SILVER Star
I've used high angle years ago his prices were high back then but he was the only one making drive shafts for big lifted trucks one being f250 with 22 inches of lift back then. Got both shafts from Tom for a swap I'm doing for 1100 double cardian front and rear with shipping.
