56 Cab off... rust issues
My son and I removed the cab ... it's got rust issues on all 4 corners. I'm gonna order patch panels .... any links or advice on repairing these areas would be great. Thanks

Re: 56 Cab off... rust issues
I would do it with the cab bolted to the frame. I would have the doors on and adjusted before the rear corners. Then you can check door gap before you weld. The front corners tac weld and test fit front fender with doors on. If you don't test fit you might have to cut and move and make more work. The front fender lower rear mount should be held in a little to allow room to shim and adjust the fender.

Re: 56 Cab off... rust issues
like pdw said...get the doors on and fitting
I'm guessing with that much rust your gonna have to replace the floor pans also.. after you get the doors working you also need to internally x brace the cab front to back , side to side...then verify the doors still work...

Re: 56 Cab off... rust issues
like said, install the doors and get them to fit. check the hinges to make sure they are not worn out. you can rebuild them yourself if not bent or rusted too badly. anyway, install the doors and then get them to fit properly. themn brace the cab so it can't flex. when I did mine I installed a horizontal brace across the door openings inside the cab above the floor so a 2x4 would fit there and still be above the floor. that way you can lift or support the cab using 2x4's run through under the brace. this would be handy for you if you need to do floor work. the 2x4's can be long enough to extend far out and be set down on saw horses. that gives lots of room to work on the floor. I also ran a horizontal brace across the top of the windshield area. then cross braced the doors and across the front and rear, side to side. all this while the doors are on and fitted so you know whatever you do after this won't affect the door fitment. then you can remove the doors and work on the hinge pillars or firewall or floor, whatever. I always say take lots of pics with dimensions so later you can refer back. if doing the floor area by the hinge pillar (common) you would do yourself a favour by center punching a mark on the hinge pillar, on some good sheet metal above the floor, at a full number dimension like 6 or 8" above the floor. make note of that with a pic. then you can always get the proper floor height later. also, if doing a hinge pillar, make yourself a pattern, from some solid material like plywood or sheet metal, of the pillar outside contour so after cutting and while fitting the new part you will be confident that the door seal will fit proper and the hinge location will be correct. a quick pic showing the dimension between the top and bottom hinge would also be a benefit later.
looks like you will be doing the cowls, hinge pillars, steps, front fender mounts, floor parts and rear cab corners as a minimum. maybe front cab mounts as well. take pics as you go because the hinge pillar parts can be confusing when you go to assemble. here are few pics so you know what to expect when you start the cowl job. also what I did for a firewall because I didn't wanna fill the 9 million holes perforated through by the previous owners. if your floor is bad in the front cab mount area be sure to keep the proper dimension according to the frame mounts. this will have a bearing on the door fitment as well afterwards. |

Re: 56 Cab off... rust issues
here's a few more shots to show how things go together. make sure to install the hinges and later the doors. also remember the hinge pillar part sets the height for the step part and the step has a bearing on the front edge of the door and fender fitment later. if the step is too far forward then the lower edge of the fender will butt against it or too far back and there could be a large gap to fix.
nice to see your helper is safety conscious. nice glasses and gloves. all he needs is a clipboard, a cell phone and a white helmet so he can run the show, haha. |

The floor is pretty solid.... those lowers are really bad.. is this a nightmare to repair?

Re: 56 Cab off... rust issues
biggest thing is you need to cut it back to some solid metal...take your time welding...use only spot welds...don't try to weld a bead...make sure of all your alignments before you start welding...your joints butt welded are best, although I have seen people do lap welds...if you've never welded sheetmetal before its a new experience...

Re: 56 Cab off... rust issues
Those areas needed replacing in that area on my truck but yours look a little worse than mine. I took detailed photos of all the metal work I did and it's in my build thread. I think you might get some ideas if you go through it. Link is in my signature.
