Re: My 1970 GMC Project
Hello everyone. I spent an hour in the shop after work today and managed to get my floor pan close to fitting. Still gotta beat it around a bit more yet and do a little trimming.

Re: My 1970 GMC Project
Nice work. Ton of metal repair you're having to do. You may not be happy with your welds, but I'm really impressed with your cuts. They seem super precise. What are you using?

Re: My 1970 GMC Project
Very cool stuff! I like the vise grips! I was going to do that but after looking at harbor freight the price was too good. The progress you are making is making me jealous! At this rate you will be done in no time!!

Re: My 1970 GMC Project
Well Ive been busy the last couple weeks in the garage, unfortunately not working on my truck though. Not till today anyway. I did a good clean and decided that two toolboxes was pretty overkill, so I sold the smaller one and extended my bench. After a little bit of electrical work, I got myself setup with a mini fridge in the shop!

Re: My 1970 GMC Project
Back at it. The last couple evenings Ive been in the garage working on the truck. Ive got most of the floor pan welds ground down. Then I really took some time comparing the arch of the new floor pan to the passenger side and found out that the new floor pan has a 3/8" high dome to it. So I have been heat shrinking the dome down to where it needs to be so the cab support bracket will fit properly to it. Its proving to be alot of work but it is definatly worth it. Now I get to take all the wrinkles out of the aftermarket floor pan and it is starting to look more like factory now.

Re: My 1970 GMC Project
Dude you are a brave soul for taking on that cab, kudos to you. It looks like you are getting the welding down, honestly the hardest part (in my opinion) with patching is knowing how to get the new metal to fit right and it looks like you have that part down. Are you using anything to seal up the raw metal in some of those pockets before you cover them up?

Re: My 1970 GMC Project
Your repairs are looking good. Chasing pinholes can take forever. If you didn't hammer stretch out the weld seams, that will contribute to the floor becoming crowned. (Though, I have found that reproduction pieces aren't perfect). The long weld seams shrink along the length of the seam. That causes the metal in the center to buckle and crown, because it has no where to go. You can usually hammer out a seam, and only need minimal shrinking in the center. But hey, I understand, that is a hard seam to reach and hammer out. The more experience you get at working and welding sheet metal, you will learn how it behaves.

Re: My 1970 GMC Project
More good news! We were tearing out a poorly built mezzanine at work yesterday and I scored 2 new light fixtures for the garage. So I called my dad over last night and we got them up. Almost need sunglasses now
![]() As for the truck, Ive been slowly chasing pinholes from the damn flux core ![]() ![]() |

Re: My 1970 GMC Project
Nice! I like the new shiny metal... make the rest of the floor look like that! Did you get any "oil canning" on that floor pan after you got it all welded in? What's the process of getting your supports in - are you going to have to reinstall the brace from back of cab to front first? Or weld in your supports first?
Btw did you get another blast of winter up there? We did last week and today was below zero with the wind. Thought we were on to the next season... |

We did get more winter, not just a blast though. It is like an explosion. We have been breaking 100 year old cold records. Currently as I type this it is -14°, -20° with wind chill. ![]() ![]() |

That sounds like a good plan for the supports. Holy cow! That's a bit cold for this time of year I'd say. We are also breaking records for the coldest temp. I need it to warm up so I can get outside and do more sanding!! |

Re: My 1970 GMC Project
Got some more rust cut off. I started on the passenger side and got most of the rocker cut off and started drilling out the cab support. I also figured that I might as well pull the seat backing plate of and get rid of any rust betweet it and the floor pan before re installing it. Hopefully by next weekend the rest of the cab support is out.

Re: My 1970 GMC Project
Lots of progress made in the last two days. We are a little slow at work right now so I decided to take an unpaid day off yesterday. Which meant GOODBYE RUSTY CAB SUPPORT
