Hello all, im about to replace the floors on my 55 and wondering if i have to support the cab by tacking in beams(front, back ,side, etc).? Thans

 

If you are going to take the cab off the frame and do a full replacement then I'd definitely tack in bracing N-S and E-W as well as a couple diagonals. Last thing you want is to have it come out not square, the floor provides a lot of the squaring. Another alternative is to replace the floor in two 1/2s front and rear then seam them down the center. IMO the best way would be to bolt the new floor to the squared and leveled chassis with temporary solid spacers in place of the rubber mounts. Set the body over it, center it, level the sills, square the diagonals, then attach the floor to the body. That way you have accounted for any variations the chassis aquired over the years.

Just saw your gallery, see my comment in your intro topic.

 

Kevin,

I agree with AX... do them 1/2 at a time... front half then back half...

tack weld some cross braces from door frame to door frame to keep the cab from spreading THEN makes your cuts and replacements... I used 14 guage metal for mine.... here' some info

floor fix

later

Thanks for the info guys, ill will bace the cab. It does make sense to do the front halve first then the rear and weld them at the middle. The first 55 has very solid floors, so i may acually cut them out and use them to save on costs.John your article on your floors was great, it helped alot.
Thanks
Kevin
