Time for paint, no need for showing the test fit.  It is not that great at the door jam. I'll deal with it when the suspension is in.

April 2014 I installed the quarter but it was much more difficult.  I had to work to match the Dutchmen, Roof skin and taillight panel.  I even used a trailer load bar to push the quarter into a better position by spreading it between the outer firewall and the door jam. I dont like how this lined up so I need to readdress the quarter when it is on the wheels. Again, the fit was much closer on the suspension.

June - August 2014
Its time to tackle the taillight panel.  This seemed fairly straightforward because I had solid reference points. I switched to another spot weld remover from Eastwood that made the process easier.  This tool was a two piece pilot bit and cutting head. It was at this time I decided to also replace the cross-member piece since it too had rot holes and I was already deep into the replacement mode. This probably wasnt necessary but it did bring focus on a slight twist of the mounting bracket on the frame end that I could more easily fix.

Time to paint the motor. The motor was assembled in December but I did not have a warm place for paint so I had to wait for the spring.  It was my first time painting in years.  I must have washed that motor 5 times.  I used degreaser, simply green and a phosphoric acid.  I painted the motor when assembled only because I did not have the time to do it in pieces.  I used the Chrysler blue motor paint from Eastwood with a urethane catalyst.  I decided not to prime the metal based on their suggestions.  It was a learning experience with my new gun.  I painted Chrysler blue on all original parts and silver on replacements. There was some orange peel and a couple runs but I kept it as is. Ill also be putting a satin clear cot on the intake.

October 2014 Well I thought that it was time to gauge where I was with the project and get a few quotes from local shops to finalize a few pieces of metal work and paint.  Well that put things into perspective and I decided that it was time to take on the next challenges. I received great advice that they all wanted the body on the wheels so I switched over to restoring suspension parts. I bought the reinforcement kits for the K-frame and LCAs and set to cleaning and welding.
I began working on the rear seat floor pans.  One of the previous owners had replaced one side with a patch and used a lap joint technique that was not that great and was a high risk for trapping moisture.  I tried to correct it and struggled with my welding.  I switched over to the passenger side and quickly ran into an issue that every time I tried to patch a hole I would burn through.  This was more than surface rust.  I hand fabricated the patch and it turned into three patches. Ugly, and time for something new.

As I was removing the drive train I had to deal with a previous owners repair.  For some reason, the passenger side pivot pin was welded to the K-Frame.  I had to dislodge this and then repair the hole which had become elongated.  I tried to weld the hole by inserting a copper pipe into the hole so not to get any slag into the tube.  Not overly successful because the copper was not sturdy enough but I also welded a grade 8 washer to reinforce these holes.  I dont know why these werent included in the reinforcement kit but maybe I had a unique wear point.

I guess its time to point out that my welding had not been that great to this point.  I had bought a Lincoln Mig 145 welder.  I started welding with a .035 Flux core wire which I later learned to be a bad wire choice for the thinner metals.  I had used this for spot welds to this point but they were real ugly.  Its been said before that the best way to weld is Clean Metal and practice, practice, practice.  However what I had not noted was the importance of wire choice.  I learned that the wire I was using was too big which is why I often burned through. The wire was great for 3/16 and bigger and for dirty metal like the K-frame.  I later learned that the smaller .025 and .030.  was further enhanced with gas, I use Co2, was far better.
And now back to the K-frame.  I spent a lot of time cleaning it with degreaser, gasoline, simply green, lacquer thinner and even a propane torch.  I learned to clean parts with a Phosphoric acid before painting to attack any last pieces of rust that I could not see.  I also began using an Eastwood PrePaint product that I have come to rely on after using it on the K-Frame. After all that cleaning, this product still removed residue.
As recommended in various articles and Firm Feel, I re-welded spot welds and tried to refresh the welds and seams.  I also installed the steering box reinforcement plates.  This was a challenge given the ever oozing of oil and grease.  I probably should have had the K-frame dipped.

Thanks.  It has its ups and downs but I'm learning each time I pick up the hammer/dollie and welder.  I really like your front spoiler project.  I'll probably reach out to you when its time to consider one.

I know the feeling, every new project is a chance to learn a new skill set. The spoiler deal allowed me to exercise a number of skills and I am completely amazed it came out anywhere near what I was thinking.

Here are pictures of the KFrame before welding reinforcements.

As for the LCAs, I removed the pivot pins.  I did not have a press so a friend and I decided to use a wheel puller and push the pin out.  This was no easy task and Im sure a press would have been better.  Once the pin and rubber was out I then sand blasted the arms.  I then cleaned and primed them before welding in the reinforcement plates.  I plan on installing a front sway bar but this is best done when the vehicle is at ride height. 
A little side note that I later learned that you have to remove the cup that holds the bushing for the pivot pin.  My removal process did not do this.  I chose to put in urethane bushings and when those are used you have to reuse the cups.  If the replacement rubber OEM bushings are used than the cup needs to be removed.  There is a great article in Mopar Muscle explain how to do this if you have a press.

Looking good, are you going to weld up the K frame and reinforce the steering box? Now is a real good time to do it.

My pictures are out of order.  The previous Kframe pictures have the reinforcements in place, ugly, but in place.  I took pictures of the Kframe with the phosphorous on it just before painting.  I need to find my pictures of the reinforced LCA's.  After I saw your video I realized that the LCA's my need tightening.

I did an epoxy primer then a Eastwood Detail Grey (spray gun) and a satin clear coat (Eastwood two part rattle can). I can't get pictures small enough but will try other means if others want something specific.
