Driveshaft
Hello. I will be removing the driveshaft in my 69. I believe you are to mark the shaft before removal so that it goes back in the same. My question is if that is necessary if you plan to have the driveshaft balanced? I also read somewhere that the front or rear of the driveshaft must remain that way and no switching ends (by some strange reason or accident). Is that true and why?Thanks and take care

I'm pretty sure, at one time, long before the internet. I removed my driveshaft and didn't know I was supposed to mark it. Humm. Never had issue.
about 2 years ago I was chasing a vibration. Was trying absolutely everything. Maked carefully the shaft. Including the orientation of yoke to yoke. So as not to put it on 180 out. As well as end to end. Had the shaft balanced with.the transmission yoke attached.
Still had a vibration. Removed shaft. Flipped end to end with transmission yoke reattached. Had it balanced again. Still had a vibration, kept chasing it and finally found the problem.
Still running the drive shaft flipped end to end. No issues.
.if your going to rebalance. Pull the yoke out of the trans. Reattach it. Have it balanced. Mark it carefully and put the yoke back in the transmission. On install make certain you don't attach 180 out on the yokes.

Any RWD car/truck; not just corvette.
Driveshaft CAN become bent / twisted (even ever so slightly that you cannot see it). Local driveshaft shop can detect it and can often repair it And rebalance it.
Before pulling shaft: suggest a few paint marks along shafts components and diff; helps to maintain orientation.
