driveshaft runout and correction vid
First I want to thank all these that have left info around on here for me to find related to this topic. Sorry if I missed anyone!

the drawings and part numbers associated have been quite valuable.
I figure this crosses directly to c5 drivetrain *my set up apparently IS c5 but hey i have a c6 and had to post it somewhere!
I bought a second hand drive shaft fully assembled with input and output and torque tube. The shaft is DSS but I am not certain of the brand of the solid aluminum couplers included.
While doing some other work, I noticed quite a WOBBLE on the input but heard that they just do that, so went ahead and installed. MEGA VIBRATION.
I took the billet ones to work and turns the surfaces are a bit out of wack says the quality department.
Talked to a couple of the manufacturers of these couplers and didn't really get anywhere for what is acceptable etc.
So then I dig around here and:
Turns out that the wobble is ONLY OK with the stock rubber couplers! Well hindsight is 2020 I felt so dumb to think any amount of wobble would be good for any of the components (or what they mount to) at engine rpm. I'm so glad for the research of others here for that.
The factory pieces also used I didn't trust either, and considering replacing any / all components was going to be out of pocket AGAIN. I wanted to at least try the shimming fix I found some had success with here.
-Assemble w/out loctite.
-mark the LOW SPOTS
-I put a couple here, and one here or there... building up the low spots with the shims
-check and re check by sliding/tapping back home into the tq tube
Eventually go to this (video below). I was surprised at how few shims it took to make a HUGE difference. Shim kit was $14 THANK YOU!

Car should be back on the road this weekend.
random side note; if you are doing an auto trans conversion from stick. make sure you cut the front of the input off. i cut just the pilot off and it was still too long, so i cut it where the wheel is sitting at. Tho i am not sure why I've been told/read on here that the auto cars either have a pilotless shaft (newer) or have the input pilot but no pilot brearing (older)
