Removing Unwanted Frame Weldments (1 Viewer)

[Drake2]

I am getting this 67 FJ40 frame ready for proper V8 mounts, new shock towers, and a Saginaw box setup but all the PO weldments had to come off first. What I found to work the best without digging into the OEM frame steel is documented in the pics below.

Using a 4" x 0.045 cutoff disc and angle grinder I scored the welds on the sides, almost down to the frame steel stopping just short as not to dig into it. On the top weld I scored it all the way across, again stopping short of the frame steel.

Once the scores were done I used a small chisel and 5lb hammer on a top corner to start the fracture and then moved to the middle of the top face.

Once there was enough room for a larger chisel ......

Now just a little grinding of the remaining PO welds and then smoothing with some flap disc action and move on to the next one.

awesome. Original frame metal looks like it is in fantastic shape

This is pretty much I did - my life was made way easier by the fact that the previous owner’s welds were so bad the mounts popped off prying with a flathead screwdriver after a light score with a grinder. Hard to believe they were holding the engine in…

going to do anything with those SAE fasteners attaching the front body mount to the frame?

Yes, it is in great shape. I am thinking that after sandblasting and powder coating it could look smooth like OEM new.

Yes, they will be replaced with proper metric fasteners.

Thanks for posting this. I just pulled my frame out to do this same thing. Its always good to see someone else doing the same thing and learn form their experience. Hopefully it goes as smooth as yours...
