Well the install is done. All in all it wasn't that bad. Had to cut on the car a bit thanks to changes made by the DOT in 74' but that was the biggest mod needed.
If you look to the right of the of the upper torsion tube you can see where I had to cut the frame. This cut had to be made to get the old beam out.

Getting the new 4" cut beam in was a bit tight, had to do a little pry bar lovin' to the shock towers to get it up and in place. Let's just say that there isn't an extra millimeter between the wheel wells and the shock towers.
Here it is with the torsion arms, spindles and shocks in.

So in the end I went back to the stock spindles. The beam gives me all the drop I want and with the castor shims behind the bottom torsion tubes the wheels are centered nicely in the fenders. At some point in the future I'll put disc brakes on the front and it's easier to find bolt on kits for the stock spindles. Also between all new tie rod ends and adjusting and tightening the steering box the steering is better than ever. All that is left to do is get an alignment though it's not too bad right now. It tracks straight and there is no shaking. I'm gonna drive it for a week or so and let things settle in, then take it in for the alignment.
Here is the end result.
