I put the drive shaft back together, having marked the original alignment of each piece including the back differential flange, both drive sections, the guibo mount, and the u-joint housing (which sides off the forward drive section). I learned the hard way a long ago when replacing a u-joint on my '71 Coupe that these drives are balanced and need to be put back exactly the same.
In my youth, I just beat on the caps to seat the u-joint. This time around, I applied some Lithium grease and used a C-clamp to press one cap until the retainer clip would seat and then turn the clamp around and do the other side.

Very controlled.
I soon discovered that the long zirt fittings are prone to breaking. So, after applying grease to each u-joint, I removed the zirt and used a small allen screw and red threadlock to seal it.
I got a bit confused bolting in the new brake compensator. I had taken photos before disassembly but initially I had the compensator 180 degrees out when I first mounted it into its housing.

I secured the rubber boot with a zip tie. Re-assembled it as one unit with the compensator, housing, rod, and linkage. Slipped it past the loosened rear muffler and aligned it next to the 2 loose brake lines. Do the brake flare fittings first with the compensator still loose which makes the alignment and threading of the fittings easier. Once the housing is bolted tight to the frame, then tighten down the brake lines.
I went to Sears and bought a vacuum pump brake bleeder with the expectation that bleeding the rears would be a solo effort...wrong!

Well, maybe if you had 3 or 4 hands.

The vinyl hose around the brake nipple would leak air rather than suck fluid from the line. The hose to the pump came kinked from the way it was packaged and liked to pull the tube off the fitting and it was too large in diameter to fit tightly on the nipple...but they include a smaller diameter tube and a connection... which likes to pull apart once it is lubricated with brake fluid

. So count them...4 hands......one to pump, one to work the bleeder wrench, one to hold together the connection, and one to secure the tube to the nipple. :

And, the bleeder is in a position where you are basically working blind.

What a mess. I waited until the boys got home from school and bled them the old fashioned way! We pumped a lot of old dirty fluid through the system
I put the drive shaft back in this afternoon. I had noticed that the pillow block had been bolted crooked to the mounting bracket. I thought it may be a good idea to let the drive find its own center. With the car still up on stands, I ran the car in 5th gear. With it still turning, I went back underneath where I loosened the 2 pillow block bolts to let it self-align and re-tightened. Thoughts on this? Is there a preferred procedure for this
One issue I have is ...How do you re-install the rubber axle bumper

In the above picture you can see the hole where it goes. But how do you work the flare end into the hole? A special tool? A sleeve of some kind? Please enlighten me
Bled the fronts. Took it for a short test drive.

No drive vibrations that I could feel....a job well done (if I do say so myself).
More work ahead......I noticed both front brake lines are cracked, every rubber boot in the front suspension is shot, bushings are all split. Yikes

My KYBs are being shipped. I want to put some miles on it before I tackle a major job. My inclination is to wait on the shocks until I am ready to do the front end. But the ride is so harsh now, I need to install the shocks. Thoughts? Advice?
