WOW, nice job! That’s a bunch of work, interested in finding out what the alignment guy says when he gets it on the rack.
Btw, what brand are your rims?
The alignment guy was very impressed with the whole kit. Everything was very easy to adjust and get dialed in.

And my Initial driveway alignment wasn't too bad. I had the camber on both wheels in the green. Using the strut rod lengths from the instructions, my left side caster was also in the green. My car has been wrecked and banged up on the right front corner, so the caster on the right was out. He had to lengthen the strut rod by about 0.25"

The toe, I had just eyeballed both wheels in.

My current wheels are part number LW50-60854A. I believe thats scott drake. The wheels in the first pictures at the top of this thread are from AFS. 17x9 up front and 17x10.5 in the back. They needed spacers to fit.

73 Grande will undergo three phase build process. Phase 1 is to make roadworthy. Phase 2 is interior/exterior restoration. Phase 3 is ++ performance.
I’m pulling my worn pitman arm, and the sucker is stuck on the splines. I’m using a 1/2 18” long breaker bar and it’s so tight I cannot tighten it anymore. I don’t have a torch but do have a small butane torch. I’ve done all the rust zappers and penetration products with no luck. Any ideas?

I don’t see anything wrong with the setup, but who knows.
I used an impact gun on mine. Grease up the threads on the pitman arm puller and zap it with the tooth rattler. I'm sure somewhere in the safety instructions they say not to do that, but I didn't read the instructions.

I suppose you could try a fork on an air hammer but that would be prying against the body of your steering gear which could damage it.

I have heard of guys cutting them off, too. Use a cutoff wheel on a die grinder to cut most of the way through the ring on the pitman arm, but not so deep you start cutting the shaft of the steering gear. The more you cut the pitman arm, the weaker it gets till it falls off.

Giantpune beat me to the punch re: using an impact wrench. Sometimes instructions just need to be ignored, heh heh. He shows a nice set of electric impact wrenches. We have a 1/2" drive Milwaukee electric impact wrench also. There is not anything I have been unable to loosen with it yet. One of the best power tools I have ever had, and "back in the day" (late 60s through early 80s) I have had a lot of nice power tools. A bit pricy, but well worth it.
