Spoke too soon. Vibration still there just at a higher speed (~75mph). Had a local shop check driveline angles and it's all good. About to throw in a stock transmission cross member and torque arm.
If it's still there after that I'm parting it out.

Stock arm and crossmember installed. Vibration still present. Going to measure distance between trans and rear and have PST make me a driveshaft. If that doesn't fix it I'm parting out

What did you actually do to fix the vibration? Other than go back to stock.
Is the driveshaft out of balance? Bent rim? Unbalanced tired?

This has been going on for years. so I have swapped:
driveshafts (had my oem one balanced, threw in a LS1 driveshaft also, now im back to OEM)
rear end (mind you, current one was inspected and rebuilt fully, axles are not bent. all new bearings, new posi, new ring/pinion.)
wheels/tires
transmission
now transmission crossmember and torque arm.
Everything that spins has been replaced minus the front stuff, but it is 100% a driveline vibration, as it is only present with the car in neutral or clutch pedal pressed down. It feels like its coming from the rear.
I find it hard to believe it is still the driveshaft, after having mine balanced and using another one from an LS car. I am out of ideas at this point. I think my last ditch effort will be to call Larry at 2nd gen engineering and see if he can diagnose it. I am 100% serious about parting out too lol. I can't drive the ****ing car. I'd be better off keeping parts I want and scrapping/parting the rest of the car and buying another one!

Also, I'm an idiot. I forgot to measure length for driveshaft while I was doing torque arm install. zzzzzzzzzzzzzzzzzzzz

Where's that tricycle rider when you need him? Maybe he can diagnose. This looks like a huge red flag to me.

Yup that's my red flag too, focusing on driveline angle stuff.

Same here. I still think it's driveline angle related.
FWIW I'd see about strapping a GoPro under the car facing the diff.
Edit:
One driveline thing not mentioned swapping was the diff yoke. Did you try different ones of those?

If it only does it in neutral and clutch in... just drive it and don't do those things?
Do you drive normally with the clutch in?

That split second of downshifting is rough with that vibration lol

I'm confused. So it vibrates all the time but worse with clutch in or in neutral (clutch out)? Details matter.

haha ok let me run it down.
In gear, accelerating, vibration does not exist.
In gear, decel, vibration is KINDA there but not very noticable.
In gear, clutch pedal down, vibration is bad.
Neutral, clutch pedal down, vibration is same as above.
Neutral, clutch pedal up, vibration is the same as the above 2.
turning engine on or off doesn't change anything

I have read that the output shaft bushing? may cause a vibration. I swapped transmissions and it didn't change. I've also had 2 spec clutches in. new flywheel too...

I'm not sure why you're doing anything other than accelerating.
What does it do when you are driving a steady speed while in gear? IE cruising down the highway

Also confirming, it doesn't vibrate when the car is not moving, clutch in (shifter not just in N), and you rev to 5-6k?

Since you never race it, why does going about 65mph matter anyways?

You have done a garbage job describing your issue.
Only happens when you're doing OVER 70 mph? Does it stop at a certain MPH? Like 85 mph?
Only when clutch is depressed or when in neutral. Same if engine is running or not.
So trans is spinning but motor isn't. That rules out clutch IMO. Sounds like trans then. When forward or backward for is applied, no issue. When it free spins there is an issue.
BLS knows the most about broken LT1 T56 trans. Maybe he knows what could be free spinning and ruining your life.
Is the trans fluid at the correct level?

The above I described only over 70 mph. Gets worse gradually above that speed. Doesn't stop.
Trans fluid should be fine I'll check when it's up in the air. I find it hard to believe 2 transmissions would have same issue but I got nothing left after driveshaft
