Truck Frames

I am restoring a 1977 F-250 4X4 highboy. The truck is surprisingly in very good condition, though the bed bolt holes do not go through the frame. Someone welded brackets on the outside of the frame and bolted it through them. My frame is 34 inches wide. Dose anyone know if the floor can be replaced with the correct one to fit my frame and bolt up properly. I have found suppliers that sell replacement floor sections but they do not ask about frame width so how would one know if it is the correct floor?

I am pretty sure that ALL 73' - 79' Effies had the same floor dimensions, so it's unlikely that you will have any problems....

just make sure you get the proper one for your wheel base. i ordered the wrong one last year from lmc trucks (trailer special?) they were good enough to switch it for me, but lesson earned.
