Started on the passenger side floor today. Figured I could get it ready as I wait for my new welder to arrive...





The front cab corner on this side looks to be solid so only the floor requires replacing.






Marked out my cut and finished drilling out the spot welds.






And removed the rusty crap




Cleaned up the cab support and coated it with rust converter



I'll give that 24 hours to do it's thing and then coat it with weld through primer.

 

so 12 hours later and the rust is turning black like it's supposed to so that's a good sign...



I'll wait another 12 hours and rinse with water and dry it really well then top coat with primer.

 

I rinsed the cab mount and dried it off. Then I coated it with weld through primer.




I also dug out my fender patch panel I saved from the wrecked F-100 I bought... and sanded it down in preparation to fix the rusty spot on the 67 fender.





I saved the back half of it as it was still in good shape and wasn't rusty. It will come in handy for the drivers side patch I need.





Just trying to stay busy until my new welder shows up....

 

With that weld through primer, do you just weld it or do you still have to clean it down to bare metal where you're welding?

 

Weld it up. that's the beauty of that product, it's called exactly what you do with it. Weld through it.

 

Thanks for clarifying. It sounded too good to be true, lol.

 

Still waiting on my new welder to show up (it's somewhere in the Midwest) so I fired up the 72 F250 parts truck and moved to a better spot to start disassembly. It looks like a really nice truck until you dig a little deeper. That's when you realize how much rust there is and that someone slapped on a bunch of bondo over rusted out body panels and painted it.









So far the good stuff has been the following:

Good bumper and stone guard (used them to fix my wrecked 69 F100)




The hood seems to be dent and rust free so that's a bonus as the 67 flatbed needs a better hood.

Good windshield (67 needs a windshield)

Also the tailgate and grill seem to be in good shape.



Engine and transmission seem to be in good working order (did a little work to it when I first got it)

And the chassis is a F250 and seems to be fine and a better fit for a flatbed then the F100 but I'll need to check that out more once I get the body out of the way.

As for more of the bad the rust seems to never stop. I keep finding more and more and more....


















It's really amazing that the drivers side cab corner was good enough to use as a patch with all of this rust everywhere.

 

Removed the the bed yesterday, took a little more effort than I was expecting but it was a lot more fun when I didn't care about damaging it (rust).




With the temps getting back into the 100's today I figured it was a perfect time to pressure wash the rear of the chassis. Get some work done and cool off at the same time.







I was happy to see a lot of the crappy undercoating blew off with the pressure washer

 

ok super excited! after my last post I figured there is still daylight and the pressure washer is still out and hooked up I'll pressure wash what I can see of the front end and make it a little cleaner to work on. Well for whatever reason I really never payed attention to the front end of this truck. It's always been a parts truck and mainly for the engine, transmission and power steering. As I'm looking under it pressure washing the crossmember moving over to the wheels I notice someone has already done a disk brake conversion to this truck! Major bonus for the 67 Flatbed chassis upgrade!





This is how the truck sits tonight. A few parts lighter and a bit more clean.

 

Great looking work. Just want to say how much I appreciate all the pictures. You clearly know what your doing, keep up the good work!

 

No problem your welcome and thanks! The way I see it is... without pictures it never happened . I can tell you all what I did but I've always learned by seeing it done so I want to make sure 1, that everything is documented and 2, help anyone who still needs to do the same repairs. I know that I appreciate the other threads on here that show things that I'm not sure about, so I'm glad to help when I can. Hopefully this helps motivate those still waiting to jump in and go for it.

 

continued pulling both trucks apart, the temperature yesterday topped out at 108 so I stayed in air-conditioned shop and pulled some of the dash apart on the 67.







Today I got outside early to beat the heat and pulled the rest of the front end off off the 72 parts truck and got ready to pressure wash it some more.







Right before I started pressure washing FedEx showed up with my new welder so I had to stop and unbox it super excided to see how this one works!





Ok so back to pressure washing after that very exciting break... well exciting for me I don't know how it was for the rest of you...







A ton of crap blown off and she's looking good! ok that's a stretch but she is cleaner. Less grease and grime to get on me .

 

bagged and tagged all the small stull from the 72 and boxed it up for the next projects.

 

Time to fire up the new welder and get the passenger floor finished. I grabbed my cut out section and a replacement panel. Lined them up together and used sheet metal screws to hold them tight. Used the old one as the templet and an edge to run my cutting wheel against.






After a bit of fine tuning and trimming I got it lined up and clamped in.




2 hours and a few thousand spot welds later it's a solid floor again.






The new welder did great and it has a spot weld setting that is nice. It lets you set it up to spot weld for as many seconds as you want to. I set it for 2-1/2 seconds and it gives you a perfect little burst each trigger pull. At first it took some getting use to and seemed kinda gimmicky as I've done a few million spot welds with my 20 year old machine just fine but I have to say I liked the setting after using it now.

 

Man you are making great progress. Also I believe those are original disc brakes for a 1972. My parts truck had the same dual piston Dayton calipers on it. Great bonus score!
