Kframe welded nuts are basically gone and all that is there is about a three inch square hole where they use to be. The rest of the frame rails are fine. Is this an easy fix or is replacing the frame rail a better option? The care is a U code so it has the welded in torque boxes which is also in great shape. I want to try and repair this without risking weakening or having the body bend on me. Anybody done this and have first hand advice as to best way to go??

You can buy a whole new rail if the area is too big and you want correct curvature,hole and nut locations and cut a patch from that.

I've seen a lot of rotted rails, it's usually down by the TB crossmember or on the section ahead of it.. The section by the K member is a new one to me, I'd wonder if it wasn't worse when you cut out the obvious bad section?

Reading your discription of having good frame rails except for some 3 inch "square" holes where the K-frame nuts use to be........Almost sounds like someone may have used a cutting torch to remove the K-frame at one point in time. Take lots of measurements from another car to locate the welded nuts back in the correct location. Unless you plan on making it an altered wheel base.

I parted a rusty 74 cuda and it rusted in the same place while the rest of the rails weren't that bad... not where I usually see them rust, but there are plates there and an area that dirt and such will stay.
