So awhile ago I posted a question asking how much it would cost to have some frame repair done. After hearing the responses I was left with the option of either abandoning this car or tackling it myself due to the cost. I had taken a welding class years ago but that's it. So I bought a welder, spot weld cutter and found the replacement parts online and jumped in the deep end of the pool. I used all goodmark replacement parts and found them to be very good! They are all high quality and matched up perfectly.
I didn't have any trouble using the Blair spot weld cutter to remove the spot welds. I removed the inner fenders and welded in the new ones (body and radiator support sides only) to kinda hold things in place and replaced the drivers side frame rail first. (the passenger rail was fine and didn't need replacing) I read on here that you can just bolt the new rail up to the K member and then its pretty much in the right location, so that's what I did. I had to measure and was having doubts about the shock tower placement, since it comes separately from the frame rail but I think I got it in the right place.
When it came to the torsion crossmember I decided to just cut out a small section of the floor so I could access the welds sandwiched between the floor and body and then cut through the floor for the rest. That worked great! I soon realized that you cannot weld sheet metal with flux core welding wire, so I am gonna have to buy gas to mig with for the sheet metal floor repair.
Anyway I was able to do all this by myself and I'm a novice for sure. In total I replaced the drivers frame rail, drivers shock tower, torsion bar crossmember, and both inner fenders for about $1000 in parts. I'm not saying it was easy by any means but it wasn't as hard as I thought it would be.
Oh and I was able to source the Mopar F3 green paint at Napa, they still had the recipe in their system and mixed it up in a few spray cans. I put down epoxy 2K primer then paint then 2K clear in the engine bay.
Maybe this will help someone else and encourage somebody to take on their own project. Feel free to ask any questions and I'll answer them if I'm able.
Feel free also to refrain from bashing my job in my single car garage on an uneven floor without a jig.

congrats....... the sheet metal only fits one way and dictates everything..... no jig required......people who have never done it love to over think it........ the cat's out of the bag.......... right @Kern Dog ?
 
Looks great! Did a similar job on my 71. Except I left the towers & aprons all attached untill after the replacement rail was in. I bolted mine to the bare K & slid it in bolting it to the passenger side as well. I measured a ton but it was pretty straight forward. I did add a 1-2" stitch of weld every 6 inches around the perimeter of everything that was replaced(where there was a flange or overlap). Its a lot of work, I know it makes you proud to look at it now.
No bashing from my end. Excellent work!
Mine was more extensive after the rail. Replaced aprons, front pan, firewall, & upper cowl.

Nice work it looks great. Can you share with me the code for the F3 paint? I was looking for some for my project.

Outstanding job!

You've done a better job than some bodyshops do.

Now you have opened up possible future project cars that everyone else is afraid of.

Now you've turned a page in your hobby. You realize that anything can be fixed and how to do it. Now you can judge wether it's worth it or not. Some of the cars I see getting parted out I would love to have.

Don't worry about people being critical. I've decided that the majority of forum experts have never picked up a wrench in their lives. They only talk about doing what you've actually done. Most guys who've actually turned a wrench will gladly offer support and advice instead of bashing.

And after you've gotten your finger prints all over a car you can say you truly own it.
 
Thanks everyone!!
It does feel good to know I was able to do it. I stood in the garage for quite awhile just looking at what I'd done.

Congratulations, on a job well done! I'm not sure I would have been up to the task myself. That car must mean alot to you to take on such an daunting task. 440'

Thank you! Not sure it means a lot to me but it's what I have. I figured if things went south I didn't have a lot into it to start with.
 
Job well done! Doing the work yourself gives one a special satisfaction that you now have.
 
Thank you so much. I had ordered some a while back and the color was way off. Keep up the good work on the 72. What is the interior color?
 
I have some extra 72 green interior parts if you need anything let met know.
